Discrete water clusters in tetra-?-cyanido-tetra-cyanidobis(1,4,7-triisopropyl-1,4,7-triaza-cyclo-nona-ne)dicopper(II)dinickel(II) tetra-hydrate.

ABSTRACT: The title tetra-cyanido-nickelate-copper complex, [Cu?Ni?(CN)?(C??H??N?)?]·4H?O, was synthesized by self-assembly using potassium tetracyanidonickelate(II) and dichlorido(1,4,7-triisopropyl-1,4,7-triazacyclononane)copper(II). The asymmetric unit contains half of a complex mol-ecule and two water mol-ecules. The entire complex has -1 symmetry and contains Ni(II) in a slightly distorted square-planar and Cu(II) in a square-pyramidal coordination environment. The crystal packing shows a discrete tetra-mer water cluster. Within the cluster, the four water mol-ecules are fully coplanar and each water monomer acts both as single O-H?O and O-H?N hydrogen-bond donor and acceptor.

Project description:The homoleptic thio-ether title complex, [Ni(C(6)H(12)S(3))(2)](BF(4))(2)·2CH(3)NO(2), shows the expeced hexa-kis-(thio-ether) octa-hedral environment around the Ni(II) atom. It crystallized as two crystallographically independent complex cations, [Ni(9S3)(2)](2+) (9S3 = 1,4,7-trithia-cyclo-nona-ne), within the unit cell where each Ni(II) lies on an inversion center. In addition to the complex cations, there are two crystallographically independent BF(4) (-) anions present to balance the charge, and each shows disorder along a pseudo-C(3) axis with ratios of 0.53?(2):0.47?(2) and 0.55?(2):0.45?(2). Two nitro-methane solvent mol-ecules per complex cation are also present in the unit cell.

Poly[[tri-μ-cyanido-cyanido(1,4,10,13-tetra-oxa-7,16-diaza-cyclo-octa-deca-ne)barium(II)platinum(II)] hemihydrate].

Project description:The title compound, {[BaPt(CN)(4)(C(12)H(26)N(2)O(4))]·0.5H(2)O}(n), is a two-dimensional coordination polymer in which the sheets are oriented approximately parallel to the (01) set of crystal planes.

Project description:In the title complex, {[Cu(2)Mo(CN)(8)(C(12)H(30)N(6)O(2))(2)]·4H(2)O}(n), the polyhedron around Mo has site symmetry with a distorted square-antiprismatic shape, while the Cu atom (2 symmetry) is in a distorted axially elongated octa-hedral coordination environment. The uncoordinated water molecule is disordered over three sites with occupancies of 0.445 (7), 0.340 (7) and 0.215 (7). Mo and Cu atoms acting as basic components are connected by an Mo-CN-Cu-NC-Mo- linkage to form a distorted diamond-like network. Additional hydrogen bonding between the N-H groups and the water molecules stabilizes this arrangement.

Project description:In the title half-sandwich compound, [Ni(C(6)H(15)N(3))(H(2)O)(3)]Br(NO(3)), the central Ni(II) ion, lying on a threefold rotation axis, is six-coordinated by three amine N atoms from the face-capping triaza macrocycle and three water O atoms in a slightly distorted octa-hedral geometry. In the crystal, O-H?O hydrogen bonding and weak O-H?Br inter-actions associate the Ni(II) cations and the counter-ions into a three-dimensional supra-molecular network.

Project description:The title compound, [CoCl(2)(C(15)H(24)N(6))(C(3)H(7)NO)], crystallizes as a monomeric complex.

Tris(propionitrile-κN)[1,4,7-tris-(cyano-meth-yl)-1,4,7-triaza-cyclo-nonane-κN,N,N]copper(II) bis-(perchlorate) dihydrate.

Project description:In the title compound, [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](ClO(4))(2)·2H(2)O, the Cu(II) atom lies on a threefold rotation axis and is coordinated in a distorted N(6) octa-hedral environment by three tertiary amines from the tridentate chelating aza-macrocyclic ligand and three propionitrile mol-ecules. Inter-molecular non-classical C-H⋯N hydrogen bonding inter-links the [Cu(C(3)H(5)N)(3)(C(12)H(18)N(6))](2+) cations into a two-dimensional supra-molecular sheet extending along the ab plane.

Crystal structure of poly[(2,2'-bi-pyridine-κ(2) N,N')tetra-kis-(μ-cyanido-κ(2) N:C)dinickel(II)].

Project description:The polymeric title complex, [Ni2(CN)4(C10H8N2)] n , was obtained serendipitously under hydro-thermal conditions. The asymmetric unit consists of one half of an [Ni(CN)4](2-) anion with the Ni(2+) cation situated on an inversion centre, and one half of an [Ni(2,2'-bpy)](2+) cation (2,2'-bpy is 2,2'-bi-pyridine), with the second Ni(2+) cation situated on a twofold rotation axis. The two Ni(2+) cations exhibit different coordination spheres. Whereas the coordination of the metal in the anion is that of a slightly distorted square defined by four C-bound cyanide ligands, the coordination in the cation is that of a distorted octa-hedron defined by four N-bound cyanide ligands and two N atoms from the chelating 2,2'-bpy ligand. The two different Ni(2+) cations are alternately bridged by the cyanide ligands, resulting in a two-dimensional structure extending parallel to (010). Within the sheets, π-π inter-actions between pyridine rings of neighbouring 2,2'-bpy ligands, with a centroid-to-centroid distance of 3.687 (3) Å, are present. The crystal packing is dominated by van der Waals forces. A weak C-H⋯N inter-action between adjacent sheets is also observed.

Project description:In the title compound, [Cr(2)Ni(C(16)H(14)N(2)O(2))(2)(CN)(4)(C(10)H(24)N(4))]·2CH(3)OH, each [Cr(salen)(CN)(2)] unit {salen is 2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolate} acts as a monodentate ligand through one of its two cyanide groups N bound to a central [Ni(cyclam)](2+) core (cyclam is 1,4,8,11-tetra-azacyclo-tetra-deca-ne). Each Cr(III) ion is coordinated by two N and two O atoms from a salen ligand situated in the equatorial plane with two trans cyanide C atoms, yielding a distorted octa-hedral coordination geometry. The Ni(II) atom lies on an inversion center and is octa-hedrally coordinated by a cyclam ligand lying in the equatorial plane and by two cyanide N atoms. The asymmetric unit contains one half of the complex mol-ecule and a methanol solvent mol-ecule. In the crystal structure, the complex mol-ecule is linked to the methanol solvent mol-ecules via O-H?O and N-H?O hydrogen bonds. Individual complex mol-ecules are linked by C-H?N hydrogen bonds, forming chains along b.
