Catena-Poly[[[{1-[(E)-phenyl(pyridin-2-yl-?N)methylidene]semicarbazidato-?(2)N(1),O}copper(II)]-?-dicyanamido-?(2)N(1):N(5)] monohydrate].

ABSTRACT: The Cu(II) atoms in the title coordination polymer, {[Cu(C(13)H(11)N(4)O)(C(2)N(3))]·H(2)O}(n), are N,N',O-chelated by the deprotonated Schiff base ligands, and adjacent metal atoms are bridged by the dicyanamide ions, generating a polymeric chain that propagates along the b axis. The two independent metal atoms show a square-pyramidal N(4)O coordination. The two independent water mol-ecules are disordered over two positions; each water mol-ecule is a hydrogen-bond donor to a carbonyl O atom. Weak N-H?N hydrogen bonding is also observed.

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[[diacetonitrile-copper(I)]-?-dicyanamido].

Project description:The crystal structure of the title compound, [Cu(C(2)N(3))(C(2)H(3)N)(2)](n), features zigzag chains along the a axis that consist of alternating [Cu(MeCN)(2)] and dicyanamide units, the latter acting as bidentate ligands via both terminal N atoms. The Cu atom shows a slightly distorted tetra-hedral coordination sphere. The anionic and neutral ligands lie on different mirror planes (perpendicular to the b and a axis, respectively), while the Cu atom is situated on their inter-section. The asymmetric unit comprises one fourth of the formula unit.

catena-Poly[[[diaqua-copper(II)]-{?-4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoato}] monohydrate].

Project description:The asymmetric unit of the title polymeric compound, {[Cu(C(22)H(18)N(2)O(4))(H(2)O)(2)]·H(2)O}(n), contains a Cu ion situated on an inversion center, half of a centrosymmetric 4,4'-[1,4-phenyl-enebis(methyl-eneimino)]dibenzoate ligand, a coordin-ated water mol-ecule in a general position and an uncoordin-ated water mol-ecule situated on a twofold rotation axis. The distorted octa-hedral coordination geometry of the Cu(II) ion is formed by six O atoms. The -NH- groups of the ligand are involved in intra-molecular N-H?O hydrogen bonds, while the water mol-ecules participate in the formation of a three-dimensional supra-molecular framework via inter-molecular O-H?O hydrogen bonds.

Project description:The crystal structure of the title compound, {[Na(C(7)H(5)ClNO(2))(H(2)O)(3)]·H(2)O}(n), features polymeric chains along [010]. The Na(+) cation is octa-hedrally coordinated by four bridging water mol-ecules, a terminal water mol-ecule and an O atom derived from a monodentate carboxyl-ate ligand. Adjacent polyhedra share two O?O edges. The polymeric chains are linked into a three-dimensional network via O-H?O and O-H?N hydrogen bonds.

catena-Poly[[(benzil bis{[(pyridin-2-yl)methylidene]hydrazone}-??N,N',N'',N''')mercury(II)]-?-chlorido-[dichloridomercury(II)]-?-chlorido].

Project description:In the title coordination polymer, [Hg?Cl?(C??H??N?)](n), one Hg(II) ion is coordinated by four N atoms from the benzylbis((pyridin-2-yl)methyl-idenehydrazone) ligand and two Cl? ions in a very distorted cis-HgCl?N? octa-hedral geometry. The other Hg(II) ion is coordinated in a distorted tetra-hedral geometry by four Cl? ions. Bridging chloride ions link the Hg(II) ions into a chain propagating in [010]: the Hg-Cl bridging bonds are significantly longer than the terminal bonds. The dihedral angle between the central benzene rings of the ligand is 83.3?(2)°. The packing is consolidated by weak C-H?Cl hydrogen bonds and C-H?? inter-actions.

catena-Poly[[bis-(acetato-?O)aqua-copper(II)]-?-5-(pyridin-3-yl)pyrimidine-?N:N].

Project description:In the title compound, [Cu(CH(3)CO(2))(2)(C(9)H(7)N(3))(H(2)O)](n), the Cu(II) ion is penta-coordinated in a square-pyramidal geometry. The N atoms of the two chelating symmetry-related 5-(pyridin-3-yl)pyrimidine ligands and the O atoms of the two monodentate acetate anions are nearly coplanar, with a mean deviation from the least-squares plane of 0.157?(2)?Å and the Cu(II) ion is displaced by 0.050?(3)?Å from this plane towards the apical water O atom. Bridging through the bis-monodentate 5-(pyridin-3-yl)pyrimidine ligand forms a one-dimensional coordination polymer extending parallel to [010]. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a two-dimensional supra-molecular structure parallel to (100). The crystal studied was an inversion twin with a 0.57?(3):0.43?(3) domain ratio.

The Cu(II) atom is located on a centre of inversion and has an elongated octa-hedral coordination geometry formed by four N atoms from four symmetry-related btp ligands and two coordinated water mol-ecules. Adjacent Cu(II) atoms are connected by btp ligands, generating a double-stranded chain. The nitrate anion is disordered over two positions in a 0.828?(7):0.172?(2) ratio.
