Crystal structure of aqua-1κO-{μ-2-[(2-hydroxy­ethyl)methylamino]ethanolato-2:1κ4O1,N,O2:O1}[μ-2,2′-(methylimino)diethanolato-1:2κ4O,N,O′:O]dithiocyanato-1κN,2κN-chromium(III)copper(II)

[Cr(μ-mdea)Cu(μ-Hmdea)(NCS)2H2O], (where mdeaH2 is N-methyldiethanolamine) is formed as a neutral heterometal CuII/CrIII complex whose molecular structure is based on a binuclear {CuCr(μ-O)2} core. In the crystal, the binuclear complexes are linked via two pairs of O—H⋯O hydrogen bonds to form inversion dimers, which are arranged in columns parallel to the a axis.

Bis(2,9-dimethyl-1,10-phenanthroline)copper(I) penta-cyanido-nitro-soferrate(II).

The asymmetric unit of the title complex [Cu(C14H12N2)2]2[Fe(CN)5(NO)], consists of a [Cu(dmp)2]+ cation (dmp is 2,9-dimethyl-1,10-phenanthroline) and half an [Fe(CN)5(NO)]2− anion. The anion is disordered across an inversion center with the FeII ion slightly offset (ca 0.205Å) from the inversion center in the direction of the disordered trans-coordinating CN/NO ligands. The anion has a distorted octahedral coordination geometry. The CuI ion is coordinated by two phenanthroline ligands in a distorted tetrahedral geometry. The dihedral angle between the phenanthroline ligands is 77.16 (4) Å. In the crystal, the cations are connected to the anions by weak C—H⋯N hydrogen bonds. In addition, weak π–π stacking interactions are observed, with centroid–centroid distances in the range 3.512 (3)–3.859 (3) Å.

Tris(N-{bis­[meth­yl(phen­yl)amino]­phosphor­yl}benzene­sulfonamidato-κ2O,O′)(1,10-phenanthroline-κ2N,N′)lanthanum(III)

A lanthanum(III) complex with formula LaL 3Phen (where L − is the sulfonylamidophosphate (SAPh)-type ligand N-{bis[methyl(phenyl)amino]phosphoryl}benzenesulfonamidate, C6H5SO2NHPO[N(CH3)C6H5]2 has been synthesized and its crystal structure determined.

Crystal structure of aqua­tris­{μ-N-[bis(diethyl­amino)phosphoryl]-2,2,2-tri­chloroacetamidato-κ3O,O′:O}calciumsodium

In the title compound, three ligands are coordinated to the Ca2+ ion in a bidentate-chelated manner via the O atoms of the CO and PO groups. The sodium ion is encapsulated between three chelated metallacycles {CaL}(where L − = Cl3CC(O)NP(O)[N(C2H5)2]2) due to the bridging function of the carbonyl O atoms and it is capped by the water molecule.

Bis[chloridobis(1,10-phenanthroline)copper(II)] penta­cyanido­nitro­soferrate(II) di­methyl­formamide monosolvate

The title complex [CuCl(C12H8N2)2]2[Fe(CN)5(NO)]·C3H7NO, consists of discrete [Cu(phen)2Cl]+ cations (phen is 1,10-phenanthroline), [Fe(CN)5NO]2− anions and one dimethylformamide (DMF) solvent molecule of crystallization per asymmetric unit. The CuII atom is coordinated by two phenanthroline ligands and one chloride ion in a distorted trigonal–bipyramidal geometry. The dihedral angle between the phen ligands is 77.92 (7)°. The cation charge is balanced by a disordered nitroprusside counter-anion with the FeII atom located on an inversion center with a slightly distorted octahedral coordination geometry. In the crystal, weak C—H⋯N and C—H⋯Cl hydrogen bonds connect anions and cations into a two-dimensional network parallel to (100). In addition, π–π stacking interactions are observed with centroid–centroid distances in the range 3.565 (2)–3.760 (3)Å. The dimethylformamide solvent molecule was refined as disordered about an inversion center.
