Poly[bis-(μ(2)-formato-κO:O')(quinoxaline-κN)copper(II)].

ABSTRACT: In the polymeric title copper(II) compound, [Cu(CHO(2))(2)(C(8)H(6)N(2))](n), both formato ligands are O-bidentate anions and act as bridging ligands, creating a planar polymeric arrangement. The slightly distorted square-pyramidal coordination around Cu(II) comprises four O atoms from two different formate anions as the base and a quinoxaline mol-ecule in the apical position.

The perchlorate anion is disordered over two positions with an occupancy ratio of 0.628 (9):0.372 (9).

Project description:The title compound, [Cu(C(2)O(4))(C(5)H(8)N(2))(2)](n), is composed of one-dimensional linear chains running parallel to the a axis. In the chain, trans-[Cu(imidazole)(2)](2+) units are sequentially bridged by bis-bidentate oxalate ligands, resulting in an octa-hedral CuO(4)N(2) donor set. The Cu⋯Cu separation through the oxalate bridge is 5.620 (5) Å. Both the Cu atoms and the C-C bond of the oxalate bridge are bis-ected by inversion centres.

Di-μ-nitrito-κO:O-bis-[bis-(1-ethyl-1H-imidazole-κN)(nitrito-κO)copper(II)].

Project description:In the structure of the title compound, [Cu(2)(NO(2))(4)(C(5)H(8)N(2))(4)], the asymmetric unit consists of two moieties containing one Cu ion, two nitrite ions and two 1-ethyl-1H-imidazole mol-ecules associated via weak Cu-O inter-actions. Each Cu(II) atom displays an elongted square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion in the basal plane. The dimeric units are linked into a three-dimensional network by C-H⋯O hydrogen bonds.

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.

Project description:The title compound, [Ni(C(2)O(4))(C(5)H(5)N)(2)](n), was synthesized under hydro-(solvo)thermal conditions. The Ni(II) atom, lying on a twofold rotation axis, has an octa-hedral coordination geometry involving two N atoms from two pyridine ligands and four O atoms from two oxalate ligands. The Ni atoms are connected by the tetra-dentate bridging oxalate ligands into a one-dimensional zigzag chain.

A second polymorph of aqua-(2,9-di-methyl-1,10-phenanthroline-κN,N')bis-(formato-κO)copper(II).

Project description:A new monoclinic polymorphic form of the title compound, [Cu(HCO(2))(2)(C(14)H(12)N(2))(H(2)O)], is described. It differs from the first ortho-rhom-bic polymorph [Pan, Lin & Zheng (2005 ▶). Z. Kristallogr. New Cryst. Struct.220, 495-496] in the deviation of the Cu atom relative to the plane of the 2,9-dimethyl-1,10-phenanthroline (dmp) ligand. In the present structure, the Cu atom is shifted from the mean plane of the dmp ligand by only 0.005 (1) Å, compared with 0.318 (6) Å in the ortho-rhom-bic form. Hydrogen-bonding and π-π stacking inter-actions (mean inter-planar distance of 3.59 Å in the title compound) in the two different polymorphs are both essential to the supra-molecular assembly.

catena-Poly[[bis-(nitrato-κO,O')copper(II)]-μ-2,2'-(ethane-1,2-diyldithio)di-1,3,4-thia-diazole-κN:N].

Project description:In the title compound, [Cu(NO(3))(2)(C(6)H(6)N(4)S(4))](n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by two N atoms of two 2,2'-[1,2-ethane-diyl-bis-(thio)]bis-[1,3,4-thia-diazole] ligands in trans positions, and four O atoms from two symmetry-related opposite nitrate anions, which are asymmetrically bonded, resulting in a strong distorted octa-hedral geometry of the central atom. The ethane group is equally disordered over two sites via another inversion centre. The bridging bidentate 2,2'-[1,2-ethanediylbis(thio)]bis-[1,3,4-thia-diazole] ligands link the Cu(II) centres into a one-dimensional chain. The chains are inter-connected via inter-molecular S⋯O inter-actions [3.044 (4) and 3.084 (5) Å] and weak C-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular structure.

Project description:In the title compound, [Pd(C(7)H(7)O(3)S)(2)(C(13)H(14)N(2))(2)](n), the metal ion, located on a twofold rotation axis, exhibits a slightly distorted octa-hedral coordination environment, with bond angles that deviate by at most 2.2° from an ideal geometry, completed by two O atoms from two deprotonated p-toluene-sulfonic acid ligands and four N atoms from four 1,3-di-4-pyridylpropane ligands.

Project description:In the title compound, [Pd(C(8)H(4)O(4))(C(7)H(6)N(2))(2)](n), the Pd atom is tetra-coordinated by two carboxyl-ate O atoms from two benzene-1,4-dicarboxyl-ate (bdc) dianions and two N atoms from two benzimidazole ligands, resulting in a slightly distorted tetra-hedral PdO(2)N(2) geometry. The bdc ligand acts as a bridge, linking the Pd atoms into a chain. Inter-chain N-H⋯O hydrogen bonds help to stabilize the crystal structure.

catena-Poly[[(4-methyl-benzoato-κO)manganese(II)]-μ-aqua-bis-(μ-4-methyl-benzoato-κO:O')[(4-methyl-benzoato-κO)manganese(II)]-bis-(μ-N,N-diethyl-nicotinamide)-κN:O;O:N].

Project description:The asymmetric unit of the title complex, [Mn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)(H(2)O)](n), contains two crystallographically independent units. In each one, the Mn(II) ions are bridged by two 4-methyl-benzoate (PMB) ligands and one water mol-ecule. In the crystal structure, each Mn(II) ion is coordinated by three PMB ligands, one water mol-ecule and two symmetry-related N,N-diethyl-nicotinamide (DENA) ligands. Symmetry-related Mn(II) ions are bridged by the N and O atoms of symmetry-related DENA ligands, forming polymeric chains parallel to [100]. The coord-ination environmnts for the Mn(II) ions are slightly distorted octa-hedral. Intra-molecular O-H⋯O hydrogen bonds link bridging water mol-ecules to the carboxyl-ate O atoms of a neigh-boring polymeric chain. In the crystal structure, π-π contacts between benzene rings [centroid-centroid distance = 3.562 (1) Å] and weak C-H⋯π inter-actions are also observed.
