Catena-Poly[[bis-(4-methyl-pyridine-?N)cobalt(II)]-di-?-dicyanamido-?(2)N(1):N(5)].

ABSTRACT: Cobalt(II) nitrate hexa-hydrate and sodium dicyanamide self-assembled in dimethyl-formamide (DMF) and 4-methyl-pyridine solutions to form the title compound, [Co(C(2)N(3))(2)(C(6)H(7)N)(2)](n). The Co(2+) ion lies on an inversion center and adopts an octa-hedral coordination geometry in which four N atoms from four different dicyanamide ligands lie in the equatorial plane and two 4-methyl-pyridine N atoms occupy the axial positions. The Co(II) atoms are connected by two bridging dicyanamide ligands, resulting in a chain parallel to the c axis. The chains are connected into a three-dimensional network by C-H?N hydrogen bonds.

catena-Poly[[bis-(pyridine-κN)cadmium]-di-μ(2)-thio-cyanato-κN:S;κS:N].

Project description:The asymmetric unit of the title compound, [Cd(NCS)(2)(C(5)H(5)N)(2)](n), consists of two crystallographically independent Cd(II) cations, four thio-cyanato anions and four pyridine ligands. The Cd(II) atoms are each coordinated by four N atoms from two pyridine ligands and two thio-cyanato anions, each in a mutually cis orientation, and by two S atoms from two adjacent thio-cyanato anions within a slightly distorted octa-hedral coordination environment. The Cd(II) atoms are μ-1,3-bridged via the thio-cyanato anions into polymeric chains parallel to [001]. The Cd(II)⋯Cd(II) intra-chain separations range between 5.9688 (6) and 6.0195 (6) Å, whereas the shortest Cd(II)⋯Cd(II) inter-chain separations are 7.8272 (7) and 8.6312 (6) Å.

catena-Poly[[bis-(pyridine-κN)zinc]-μ-5-carb-oxy-benzene-1,3-di-carboxyl-ato-κ(2) O (1):O (3)].

Project description:The title one-dimensional coordination polymer, [Zn(C9H4O6)(C5H5N)2] n or [Zn(HBTC)(py)2] n , (I), where BTC is benzene-1,3,5-tricarboxylate and py is pyridine, is a solvent-free polymorph of [Zn(HBTC)(py)2]·2C2H5OH [Yaghi et al. (1997 ▶). Chem. Mater. 9, 1074-1076]. Differences in the spatial arrangements and supra-molecular packing of the [Zn(HBTC)(py)2] n chains in the two structures are described. The chain in (I) extends parallel to [100] and is severely puckered, with a Zn⋯Zn distance of 8.3599 (3) Å and a Zn⋯Zn⋯Zn angle of 107.516 (3)°, as a result of hydrogen-bonding inter-actions of the types O-H⋯O and C-H⋯O. There is no evidence for π-π inter-actions in (I). The differences between the solvent-free and solvent-containing structures can be accounted for by the absence of the ethanol solvent mol-ecule and the use of the converging pair of O atoms in the bis-monodentate bridging HBTC(2-) ligand in (I).

A triclinic polymorph of catena-poly[[bis-(N,N-dimethyl-formamide-κO)cobalt(II)]-di-μ-1,5-dicyanamido-κ(4)N(1):N(5)].

Project description:The title compound, [Co(C(2)N(3))(2)(C(3)H(7)NO)(2)](n), is a triclinic polymorph of the previously reported monoclinic structure [Tong et al. (2003 ▶). Acta Cryst. E59, m405-m407]. The Co(II) ion lies on an inversion centre and adopts an almost regular octa-hedral N(4)O(2) coordination geometry. Adjacent Co(II) atoms are connected by two bridging dicyanamide ligands, resulting in the formation of neutral chains parallel to the b axis. The title complex is isotypic with the Mn(II) analogue but not with the Ni(II) analogue.

catena-Poly[[[2-(pyridin-2-yldisulfan-yl)pyridine-κN,S]copper(I)]-μ(1,5)-dicyanamido].

Project description:In the title compound, [Cu(C(2)N(3))(C(10)H(8)N(2)S(2))](n), the Cu(I) atoms are connected by bridging dicyanamide ligands, forming chains parallel to [100]. Each Cu(I) atom displays a tetra-hedral coordination environment, formed by one S atom and three N atoms from one 2-(pyridin-2-yldisulfan-yl)pyridine and two dicyanamide ligands. The crystal structure is stabilized by C-H⋯N hydrogen bonds, forming a three-dimensional network.

catena-Poly[[diaqua-bis-(isoquinoline-κN)cobalt(II)]-μ-succinato-κO:O].

Project description:In the title compound, [Co(C(4)H(4)O(4))(C(9)H(7)N)(2)(H(2)O)(2)](n), the Co(II) cation, located on an inversion center, is coordinated by two succinate anions, two isoquinoline ligands and two water mol-ecules in a distorted octa-hedral geometry. The succinate anion, located across another inversion center, bridges the Co cations, forming polymeric chains running along the b axis. The partially overlapped arrangement of parallel isoquinoline ring systems of adjacent polymeric chains and the shorter face-to-face distance of 3.402 (6) Å indicates the existence of weak π-π stacking in the crystal structure. Classical intra- and inter-molecular O-H⋯O hydrogen bonding and weak non-classical inter-molecular C-H⋯O hydrogen bonding help to stabilize the crystal structure.

Crystal structure of catena-poly[[[bis-(pyridine-4-carbo-thio-amide-κN (1))cadmium]-di-μ-thio-cyanato-κ(2) N:S;κ(2) S:N] methanol disolvate].

Project description:The asymmetric unit of the polymeric title compound, {[Cd(NCS)2(C6H6N2S)]·2CH3OH} n , consists of one cadmium(II) cation that is located on a centre of inversion as well as one thio-cyanate anion, one pyridine-4-carbo-thio-amide ligand and one methanol mol-ecule in general positions. The Cd(II) cations are octa-hedrally coordinated by the pyridine N atom of two pyridine-4-carbo-thio-amide ligands and by the S and N atoms of four thio-cyanate anions and are linked into chains along [010] by pairs of anionic ligands. These chains are further linked into layers extending along (201) by inter-molecular N-H⋯O and O-H⋯S hydrogen bonds. One of the amino H atoms of the pyridine-4-carbo-thio-amide ligand is hydrogen-bonded to the O atom of a methanol mol-ecule, and a symmetry-related methanol mol-ecule is the donor group to the S atom of another pyridine-4-carbo-thio-amide ligand whereby each of the pyridine-4-carbo-thio-amide ligands forms two pairs of centrosymmetric N-H⋯S and O-H⋯S hydrogen bonds. The methanol mol-ecules are equally disordered over two orientations.

Project description:In the crystal structure of the title compound, [HgBr(2)(C(5)H(5)N(3)O)(2)](n), the Hg(II) cation is located on an inversion center and is coordinated by two N atoms from the pyrazine rings and four bridging Br(-) anions in a distorted octa-hedral geometry. The Br(-) anions bridge the Hg(II) cations with significantly different Hg-Br bond distances of 2.4775 (8) and 3.1122 (8) Å, forming polymeric chains running along the a axis. Inter-molecular N-H⋯O and N-H⋯N hydrogen bonds are effective in the stabilization of the crystal structure.
