Dichlorido[2-diphenyl-phosphanyl-N-(pyridin-3-ylmeth-yl)benzyl-idenamine-κP,N]platinum(II).

Haleden Chiririwa; Reinout Meijboom

The title compound, [PtCl2(C25H21N2P)], is a PtII complex with an NPCl2 coordination sphere in which the metal is coordinated to the imino N and phosphane P atoms of the ligand and to two chloride ions. The PtII atom is in a distorted square-planar environment and is bound to the ligand via the P and amine N atoms in a cis fashion, with the chlorine atoms located at the two remaining sites.

Dichlorido{N-[2-(diphenyl­phosphan­yl)benzyl­idene]-2-(thio­phen-2-yl)ethan­amine-κ2P,N}platinum(II) dichloro­methane hemisolvate

Haleden Chiririwa; Alfred Muller

The crystal structure of the title compound, [PtCl2(C25H22NPS)]·0.5CH2Cl2, was determined to establish the coordination properties of the (phosphanyl)benzylidene–methanamine ligand to platinum. In the unit cell two molecules of cis-[PtCl2(C25H22NPS)] are accompanied by a dichloromethane solvent molecule. The square-planar Pt2+ coordination sphere is slightly distorted with the bidentate ligand coordinated via the P and the amine N atoms, and the Cl atoms located cis at the two remaining coordination sites. Parts of the thiophene ring and the solvate molecule were modeled as disordered with occupancy ratios of 0.55 (2):0.45 (2) and 0.302 (10):0.198 (10), respectively. Weak C—H⋯Cl interactions stabilize the crystal packing.

Bis(acetonitrile-κN)dichlorido(η4-cyclo­octa-1,5-diene)ruthenium(II) acetonitrile monosolvate

Haleden Chiririwa; Reinout Meijboom; Samson O. Owalude; Uche B. Eke; Charmaine Arderne

In the title RuII complex, [RuCl2(C8H12)(C2H3N)2]·CH3CN, the metal ion is coordinated to the centers of each of the double bonds of the cyclooctadiene ligand, to two chloride ions (in cis positions) and to two N-atom donors (from MeCN molecules) that complete the coordination sphere for the neutral complex. The coordination about the RuII atom can thus be considered to be octahedral with a slightly trigonal distortion. There is also one acetonitrile solvent molecule per molecule which is outside the coordination sphere of the ruthenium atom.

Chlorido{N-[(E)-2-(diphenyl-phosphan-yl)benzyl-idene]-2-(thio-phen-2-yl)ethan-amine-κP}gold(I).

Haleden Chiririwa; Alfred Muller

The title compound, [AuCl(C25H22NPS)], crystallizes with two independent molecules in the asymmetric unit in which the thiophene fragments are disordered over two sets of sites with 0.537 (10):0.463 (10) and 0.701 (9):0.299 (9) occupancy ratios. In both cases, the thiophene ring is rotated by approximately 180° for the second component. Important geometrical parameters include Au—P = 2.235 (2) and 2.237 (2) Å, Au—Cl = 2.286 (2) and 2.292 (2) Å, and P—Au—Cl = 177.39 (8) and 172.63 (7)°. Weak intermolecular C—H⋯Cl interactions are observed in the crystal structure.

Dichlorido{N-[2-(diphenylphosphanyl)benzylidene]-2,6-diisopropylaniline-κP,N}platinum(II).

Haleden Chiririwa; Reinout Meijboom

The title compound, [PtCl2(C31H32NP)], is a PtII complex with an NPCl2 coordination sphere in which the PtII atom is coordinated to the imino N and phosphane P atoms of the ligand and to two cis Cl ions, giving a slightly distorted square-planar geometry. The P—Pt—N angle is 89.80 (5)° and the corresponding angle between the Cl ions is 87.92 (2)°.

(SP-4-2)-Chlorido{N-[2-(diphenyl-phosphan-yl)benzyl-idene]benzyl-amine-κP,N}(meth-yl)palladium(II).

Haleden Chiririwa; Reinout Meijboom

In the title PdII complex, [Pd(CH3)Cl(C26H22NP)], the PdII atom is coordinated in a slightly distorted square-planar geometry by the imino N and phosphane P atoms of the ligand, by one chloride ion and by a methyl ligand. The methyl group is trans to the N atom of the ligand.

trans-Dichloridobis[diphen­yl(thio­phen-2-yl)phosphane-κP]palladium(II)

Andrew R. Burgoyne; Reinout Meijboom; Haleden Chiririwa; Leo Kirsten

The title compound, trans-[PdCl2(C16H13PS)2], forms a monomeric complex with a trans-square-planar geometry. The Pd—P bond lengths are 2.3387 (11) Å, as the Pd atom lies on an inversion point, while the Pd—Cl bond lengths are 2.2950 (12) Å.

trans-Dichloridobis[dicyclo-hex-yl(2,4,6-trimethyl-phen-yl)phosphane-κP]palladium(II).

Isaac Buthelezi; Haleden Chiririwa; Hezron Ogutu; Reinout Meijboom

The title compound, [PdCl2(C21H33P)2], forms a monomeric complex with a trans-square-planar coordination geometry about the PdII atom which lies on an inversion centre. The Pd—P bond lengths are 2.3760 (13) Å, while the Pd—Cl bond lengths are 2.3172 (14) Å. The observed structure was found to be closely related to that of trans-dichloridobis[dicyclohexyl(phenyl)phosphane-κP]palladium(II), [PdCl2{P(C6H11)2(C6H5)}2] [Burgoyne et al. (2012 ▶). Acta Cryst. E68, m404].

Dichlorido(η4-cyclo­octa-1,5-diene)bis­(propane­nitrile-κN)ruthenium(II)

Haleden Chiririwa; Reinout Meijboom

In the title complex, [RuCl2(C8H12)(C3H5N)2], the metal ion is coordinated to both double bonds of the cycloocta-1,5-diene ligand, two chloride ions (in cis positions) and two N-atom donors from two propanenitrile molecules that complete the coordination sphere for the neutral complex. The coordination around the RuII atom can thus be considered as octahedral with slight trigonal distortion.

Bis(acrylonitrile-κN)dichlorido(η4-cyclo­octa-1,5-diene)ruthenium(II)

Haleden Chiririwa; Reinout Meijboom

In the title complex, [RuCl2(C8H12)(C3H3N)2], the metal ion is coordinated to centers of each of the double bonds of the cycloocta-1,5-diene ligand, to two chloride ions (in cis positions) and to two N-atom donors from two acrylonitrile molecules that complete the coordination sphere for the neutral complex. The coordination about the RuII atom can thus be considered octahedral with slight trigonal distortion. The three C atoms of one of the acrylonitrile ligands are disordered over two sets of sites in a 0.581 (13):0.419 (13) ratio.
