Catena-Poly[[bis-(dicyanamido-?N (1))cobalt(II)]bis-{?-1,2-bis-[(1,2,4-triazol-1-yl)meth-yl]benzene-?(2) N (4):N (4')}].

ABSTRACT: In the title complex, [Co(C2N3)2(C12H12N6)2] n the Co(II) atom lies on a centre of symmetry and displays a slightly distorted octa-hedral coordination geometry. The 1,2-bis-[(1,2,4-triazol-1-yl)meth-yl]benzene ligands link adjacent metal atoms into polymeric chains parallel to the c axis, forming centrosymmetric 26-membered metallamacrocycles. The conformation of the metallamacrocycles is stabilized by pairs of C-H?N hydrogen bonds. The dihedral angles formed by the planes of the triazole rings with those of the benzene ring are 79.4?(2) and 79.1?(2)°. In the crystal, the chains inter-act through C-H?N hydrogen bonds, forming a three-dimensional network.

Project description:The title compound, 4C(9)H(6)O(6)·C(6)H(8)N(6)·2H(2)O, crystallizes in a layer structure where each sheet is composed of anellated hydrogen-bonded rings of six distinct sizes: R(2) (2)(16), R(3) (3)(18), R(4) (4)(12), R(4) (4)(18), R(4) (4)(22) and R(4) (4)(25). The two largest rings, viz. R(4) (4)(22) and R(4) (4)(25), are associated with O-H⋯N bonds from the carboxyl groups to the triazole rings. The typical head-to-tail carbox-yl-carboxyl R(2) (2)(8) motif is not observed.

Project description:In the title coordination polymer, [Fe(C(8)H(6)N(5)O(4))(2)](n) {or [FeL(2)](n),where HL = 2-[(1H-1,2,4-triazol-1-yl) meth-yl]-1H-imidazole-4,5-dicarb-oxy-lic acid)}, the Fe(II) ion, located on an inversion centre, is six-coordinated by two O atoms and four N atoms from two L(-) ligands in a distorted octa-hedral geometry [Fe-O = 2.1452?(13), Fe-N = 2.1316?(14) and 2.2484?(15)?Å]. There is an intra-molecular O-H?O hydrogen bond in each L(-) ligand. Being an effective tridentate bridging ligand, the deprotonated L(-) anions link two Fe(II) atoms, yielding a chain-like polymer propagating along [100]. In the crystal, these polymer chains are linked via N-H?N hydrogen bonds, forming a two-dimensional network.

catena-Poly[[[bis-(thio-cyanato-?N)zinc(II)]-?-1,2-bis-{[2-(2-pyrid-yl)-1H-imidazol-1-yl]meth-yl}benzene] 0.28-hydrate].

Project description:The title one-dimensional coordination polymer, {[Zn(NCS)(2)(C(24)H(20)N(6))(2)]·0.28H(2)O}(n), was obtained by the reaction of Zn(OAc)(2)·2H(2)O, KSCN and 1,2-bis-{[2-(2-pyrid-yl)-1H-imid-azol-1-yl]meth-yl}benzene (hereafter L). The Zn(II) ion shows a distorted octa-hedral coordination geometry and is coordin-ated by two N atoms from two SCN(-) anions and four N atoms from two organic ligands. The L ligands act as bridging bis-chelating ligands with cis coordination modes at the Zn(II) ion. One-dimensional coordination polymers are arranged into layers by ?-? stacking inter-actions between the imidazole rings of adjacent chains, with an inter-planar distance of 3.46?(1)?Å and centroid-centroid distances of 3.8775?(16)?Å. One of the thio-cyanate ligands is disordered over two positions with an occupancy factor of 0.564?(3) for the major component. The partially occupied water mol-ecule forms an O-H?S hydrogen bond with the disordered thio-cyanate group.
