In the title complex, [Ni(C21H17F2N3)2]2Br4·9H2O, there are two independent metal complexes per asymmetric unit and two ligands per metal complex. The structural features (bond lengths and angles) of the two complexes are almost identical. In each complex, the nickel(II) ion is coordinated in an octa-hedral environment by six N atoms from two chelating (9E)-N-({6-[(E)-(4-fluoro-benzyl-imino)-me...

In the title complex, {[Cd(CH(3)COO)(2)(C(11)H(8)N(2)O)(H(2)O)]·2H(2)O}(n), the Cd(II) ion adopts an O(5)N(2) penta-gonal-bipyramidal coordination geometry with four acetate O atoms and one water O atom at the equatorial sites and two pyridine N atoms at the axial sites. The (pyridin-3-yl)(pyridin-4-yl)methanone ligand acts in a μ(2)-bridging mode, linking the metal atoms, leading to an infinit...

The mol-ecule of the title compound, C14H13N5O2, is approximately planar (r.m.s deviation for all non-H atoms = 0.093 Å), with the planes of the two pyridine rings inclined to one another by 5.51 (7)°. The oxime group is syn to the amide group, probably due to the formation of an intra-molecular N-H⋯N hydrogen bond that forms an S(6) ring motif. In the crystal, mol-ecules are linked by pairs of...

The mononuclear copper title complex {N,N,N',N'-tetra-kis-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine-κ6N}copper(II) bis-(tetra-fluorido-borate), [Cu(C30H36N6)](BF4)2, is conveniently prepared from the reaction of Cu(BF4)2·6H2O with N,N,N',N'-tetra-kis-[(6-methyl-pyridin-2-yl)meth-yl]ethane-1,2-di-amine (tmpen) in aceto-nitrile at room temperature in air. The complex shows a distorted o...

The crystal structures of bis-[2-(pyridin-2-yl)phen-yl]rhodium(III) complexes with the metal in an octahedral coordination containing chloride and aceto-nitrile ligands, namely (OC-6-42)-aceto-nitrile-chlorido-bis-[2-(pyridin-2-yl)phenyl-κ(2) N,C (1)]rhodium(III), [RhCl(C11H8N)2(CH3CN)] (1), thyminate(1-) and methanol, namely (OC-6-42)-methanol(5-methyl-2,4-dioxo-1,2,3,4-tetrahydro-pyrimidin-1-...

The reaction of copper(I) iodide with 1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one (L, C13H19NOS) in aceto-nitrile/di-chloro-methane results in a crystalline coordination polymer, namely poly[bis-{μ2-1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one}tetra-μ3-iodido-tetra-copper(I)], [Cu4I4L2] n . The asymmetric unit comprises two ligand mol-ecules, four copper(I) ions and four iodide...

In the title compound, [Zn(NCS)2(C24H22N4O)]·C3H7NO, the Zn(II) cation is N,N',N''-chelated by one 2-({4-[2,6-bis-(pyridin-2-yl)pyridin-4-yl]phen-yl}(meth-yl)amino)-ethanol ligand and coordinated by two thio-cyanate anions in a distorted N5 trigonal-bipyramidal geometry. In the mol-ecule, the three pyridine rings are approximately coplanar [maximum deviation = 0.026 (5) Å], and the mean plane o...

Chiral coordination polymers have attracted much attention due to their special properties and significant applications. In this work, we synthesized two non-centrosymmetric ligands, N,N-bis(4-(1H-imidazol-1-yl)phenyl)-4-(pyridin-4-yl)aniline (DIMPPA) and N-(4-(1H-imidazol-1-yl)phenyl)-4-(pyridin-4-yl)-N-(4-(pyridin-4-yl)phenyl)aniline (MIDPPA), via structural modification of two reported centr...
