[1,3-Bis(4-nitrophenyl)triazenido](triphenylphosphine)gold(I)

Manfredo Hörner; Ivan Carlos Casagrande; Herton Fenner; Jörg Daniels; Johannes Beck

In the title complex, [Au(C(12)H(8)N(5)O(4))(C(18)H(15)P)], the coordination geometry about the Au(I) ion is linear, with one deprotonated 1,3-bis(4-nitrophenyl)triazenide ion, [O(2)NC(6)H(4)N=N-NC(6)H(4)NO(2)](-), acting as a monodentate ligand (two-electron donor), and one neutral triphenylphosphine molecule completing the metal coordination. The triazenide ligand is almost planar (r.m.s. deviation = 0.0767 A), with the largest interplanar angle being 11.6 (7) degrees between the phenyl ring of one of the terminal 4-nitrophenyl substituents and the plane defined by the N=N-N triad. The Au-N and Au-P distances are 2.108 (5) and 2.2524 (13) A, respectively. Pairs of molecules generated by centrosymmetry are associated into a supramolecular array via intermolecular C-H...O interactions, and N...C and N...O pi-pi interactions.

This study characterizes a new polymorph of the title compound, [CuCl(C18H15P)3], and analyses the influence of the extensive network of weak hydrogen-bonding interactions in the generation of this different crystal structure. The compound crystallizes in the centrosymmetric space group C2/c with two crystallographically independent molecules per asymmetric unit, in contrast with the previously determined polymorph which crystallizes in the noncentrosymmetric space group P3 with three crystallographically independent molecules in the asymmetric unit, each with crystallographically imposed C3 symmetry [Gill, Mayerle, Welcker, Lewis, Ucko, Barton, Stowens & Lippard (1976). Inorg. Chem. 15, 1155-1168]. The geometries of the two molecules of the title compound are very similar, with each having an approximately tetrahedral coordination around the central Cu atom and approximate C(s) molecular symmetry. The molecules pack in chains parallel to the crystallographic b axis, connected by C-H...Cl and C-H...pi(phenyl) hydrogen bonds.

μ-[N,N-bis(2-pyridylmethyl-1κN)-N',N'-bis(2-pyridylmethyl-2κN)-1,3-diaminopropan-2-olato]-1κN,2κN',1:2κ2O-bis(dioxovanadium)(1+) iodide dihydrate, [(VO2)2(TPHPN)]I.2H2O

Ademir Neves; Ivo Vencato; Manfredo Hörner; Herton Fenner

In the binuclear [(VO 2 ) 2 (TPHPN)] + cation of the title compound, [V 2 O 4 (C 27 H 29 N 6 O)]I.2H 2 O, the two tridentate halves of the symmetrical TPHPN − ligand are arranged so that the three donor N atoms are fac at one pseudo-octahedral metal centre but mer at the other. The strong trans influence of the oxo ligand is apparent from trends in the μ-V-O and V-N bond lengths

Darstellung und Kristallstruktur von (PhN3)2C6H4[(OH)Ni(PhN 3H)2C6H4]2 · 2THF, einem dimeren Ni(II)-Komplex mit einem überbrückenden Bistriazenido-Liganden

Manfredo Hörner; Herton Fenner; Wolfgang Hiller; Johannes Beck

Abstract (PhN3)2C6H4[(OH)Ni(PhN3H)2C6H4]2 · 2THF is obtained by the reaction of [(PhN3)2C6H4]Na2 with aqueous NiCl2. It crystallizes from tetrahydrofuran/hexane in the monoclinic space group P21/n, with a = 1574.6(3), b = 2498.5(2), c = 1629.2(2) pm, β = 93.909(3)°, and Z = 4. The Ni atoms are bridged by the bis(phenyltriazenidyl)benzene group and two hydroxyl groups. Two neutral bis(phenyltriazenyl)benzene groups chelate each Ni atom to complete the distorted coordination sphere.
