Catena-Poly[[[aqua-(propane-1,3-diamine-?N,N')copper(II)]-?-fumarato-?O:O'] monohydrate].

ABSTRACT: The asymmetric unit of the title compound, {[Cu(C(4)H(2)O(4))(C(3)H(10)N(2))(H(2)O)]·H(2)O}(n), consists of two Cu(II) atoms, half each of two propane-1,3-diamine ligands and two coordinated water mol-ecules, all lying on crystallographic mirror planes, also one fumarate dianion and one uncoordinated water mol-ecule in a general position. The Cu(C(3)H(10)N(2))(H(2)O) units are linked via fumarate dianions into a zigzag chain running along the a axis. A longer Cu-O distance [2.873?(3)?Å] is to a water mol-ecule bridging equivalent Cu(II) atoms in adjacent chains, forming a three-dimensional framework. One of the Cu(II) atoms is in a distorted square-pyramidal environment and the other is in a pseudo-octa-hedral geometry of the [5+1] type. O-H?O and N-H?O hydrogen bonds are observed in the crystal structure.

Project description:The title compound, {[Co(C(2)H(5)COO)(2)(H(2)O)]·H(2)O}(n), was synthesized by the reaction of cobalt(II) carbonate hydrate with aqueous propionic acid. The structure consists of polymeric infinite linear chains with composition [Co(C(2)H(5)COO)(4/2)(H(2)O)(2/2)](∞) running along [010]. The chains are formed by Co(2+) ions linked with bridging propionate groups and water mol-ecules, with a Co⋯Co distance along the chains of 3.2587 (9) Å. The Co(2+) ion is six-coordinated in a strongly distorted octa-hedral geometry. The chains are connected to each other by a network of O-H⋯O hydrogen bonds involving solvent water mol-ecules.

catena-Poly[[aqua-dipyridine-copper(II)]-μ-fumarato].

Project description:The title compound, [Cu(C(4)H(2)O(4))(C(5)H(5)N)(2)(H(2)O)](n), is a one-dimensional coordination polymer based on pyridine and fumarate ligands. Each Cu(II) cation is coordinated by two carboxyl-ate O atoms belonging to two fumarate anions, two N atoms from two pyridine mol-ecules and one water mol-ecule, in a square-based pyramidal geometry. Each fumarate anion bridges two Cu(II) cations through the two carboxyl-ate groups in a bis-monodentate fashion to form a one-dimensional polymeric chain along the c axis. Neighbouring chains are linked together to form a two-dimensional network parallel to the ac plane via hydrogen bonding inter-actions between uncoordinated carboxyl-ate O atoms and coordinated water mol-ecules of adjecent chains.

Project description:In the title compound, {[Co(C(7)H(3)NO(5))(C(13)H(14)N(2))(H(2)O)]·2H(2)O}(n), the Co(II) atom is coordinated by two O atoms from a pyridine-2,6-dicarboxyl-ate N-oxide ligand, two N atoms from two 1,3-di-4-pyridylpropane ligands and one water mol-ecule, and displays a distorted square-pyramidal coordination geometry. The 1,3-di-4-pyridylpropane ligands link the Co(II) atoms into an infinite zigzag chain parallel to [010]. The chains are further linked through O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

Oxalatobis(propane-1,3-diamine)manganese(II) chloride monohydrate.

Project description:In the asymmetric unit of the title compound, [Mn(C(2)O(4))(C(3)H(10)N(2))(2)]Cl·H(2)O, there are two independent Mn(III) complexes, two Cl(-) anions and two uncoordinated water mol-ecules. Each Mn(III) atom is hexa-coordinated by four N atoms from two propane-1,3-diamine ligands and two O atoms from one oxalate ligand, resulting in a slightly distorted octa-hedral MnO(2)N(4) geometry. Mn-O and Mn-N bond lengths are in the ranges 1.969 (2)-2.020 (3) and 2.068 (3)-2.113 (4) Å, respectively. There are weak inter-molecular O-H⋯O, O-H⋯Cl, N-H⋯O and N-H⋯Cl hydrogen bonds with D⋯A distances in the range 2.831 (4)-3.423 (3) Å.

catena-Poly[[[aqua-(1,10-phenanthro-line)manganese(II)]-μ-adamantane-1,3-dicarboxyl-ato] monohydrate].

Project description:In the title coordination polymer, {[Mn(C(12)H(14)O(4))(C(12)H(8)N(2))(H(2)O)]·H(2)O}(n), the Mn(II) atom has a highly distorted cis-MnN(2)O(4) octa-hedral geometry arising from its coordination by a bidentate phenanthroline ligand, a water mol-ecule and monodentate and bidentate adamantane-1,3-dicarboxyl-ate dianions. The bridging dianion leads to [001] chains in the crystal. The chains are linked by O-H⋯O hydrogen bonds, involving both the coordinated and uncoordinated water mol-ecules, thereby forming a two-dimensional network.

Project description:In the title compound, [Cd(C(6)H(4)O(8)S(2))(C(12)H(8)N(2))(2)(H(2)O)]·H(2)O, each Cd(II) ion is coordinated by four N atoms [Cd-N = 2.310 (7)-2.341 (7) Å] from two 1,10-phenanthroline ligands, one O atom [Cd-O = 2.300 (6) Å] from a 4,5-dihydroxy-benzene-1,3-disulfonate ligand and one aqua O atom [Cd-O = 2.288 (7) Å] in a distorted octa-hedral geometry. The crystal packing exhibits inter-molecular O-H⋯O and C-H⋯O hydrogen bonds and π-π inter-actions evidenced by relatively short distances [3.525 (5)-3.937 (6) Å] between the centroids of the six-membered rings of neighbouring mol-ecules.

catena-Poly[[aqua-(2,2'-bipyridine-κN,N')copper(II)]-μ-5-nitro-isophthalato-κO,O:O].

Project description:In the asymmetric unit of the title compound, [Cu(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)](n), there are two symmetry-independent one-dimensional coordination polymers related by a non-crystallographic inversion center. Within the polymers, the Cu(II )atoms, coordinated by the water mol-ecule and the chelating 2,2'-bipyridine ligands, are bridged by 5-nitro-benzene-1,3-dicarboxyl-ate dianions which act as tridentate ligands; the carboxyl-ate groups exhibit monodentate and symmetric bidentate coordination modes. The Cu(II) atoms show a strongly distorted octa-hedral coordination geometry. In the crystal structure, the two symmetry-independent coordination polymers form another one-dimensional polymeric structure via O-H⋯O hydrogen bonds between coordinated water mol-ecules and carboxyl-ate groups.

catena-Poly[[[diaqua-(1,3-benzimidazole-κN)manganese(II)]-μ-benzene-1,3-di-carboxyl-ato-κO,O:O] dihydrate].

Project description:In the polymeric title complex, {[Mn(C(8)H(4)O(4))(C(7)H(6)N(2))(H(2)O)(2)]·2H(2)O}(n), the Mn(II) cation is coordinated by two benzene-dicarboxyl-ate anions, one benzimidazole ligand and two water mol-ecules in a distorted MnNO(5) octa-hedral geometry. In the crystal, each benzene-dicarboxyl-ate anion bridges adjacent Mn(II) cations through the terminal carboxyl-ate groups, forming a polymeric complex chain along the a axis. One Mn-O(carboxyl-ate) bond is much longer than the others. In the crystal, π-π stacking is observed between nearly parallel [dihedral angle = 4.32 (6)°] benzimidazole aromatic ring systems of adjacent mol-ecules, the centroid-centroid distance between the imidazole and benzene rings being 3.5421 (11) Å. Extensive inter-molecular O-H⋯O and N-H⋯O hydrogen bonding is present in the crystal structure. The two lattice water mol-ecules are located on twofold rotation axes.

catena-Poly[[aqua-bis-(N-benzyl-adenine-κN)copper(II)]-μ-benzene-1,4-dicarboxyl-ato-κO:O].

Project description:In the title compound, [Cu(C(8)H(4)O(4))(C(12)H(11)N(5))(2)(H(2)O)](n), the Cu(II) ion is five-coordinated by two carboxyl-ate O atoms from two symmetry-related benzene-1,4-dicarboxyl-ate ligands, two N atoms from two symmetry-related N(6)-benzyl-adenine ligands and one water O atom in a square-pyramidal environment. The Cu(II) and water O atoms lie on a twofold rotation axis, and the benzene-1,4-dicarboxyl-ate ligand lies on an inversion center. The water O atom occupies the apical position and the basal plane is occupied by two O atoms and two N atoms. Each benzene-1,4-dicarboxyl-ate anion acts as a bis-monodentate ligand that binds two Cu(II) cations, forming an infinite chain extending parallel to [001]. The N(6)-benzyl-adenine ligands are attached on both sides of the chain. Neighboring chains are further inter-connected into the resulting three-dimensional supra-molecular architecture via O-H⋯O, N-H⋯O and N-H⋯N hydrogen bonds.

Project description:In the title compound, [Cu(C(10)H(8)O(6))(C(5)H(5)N)(2)(H(2)O)](n), the Cu atom is five-coordinated by two O atoms from two carboxyl-ate groups of two different 2,2'-(p-phenyl-enedi-oxy)diacetate ligands, two N atoms from two pyridine mol-ecules and one water O atom. The geometry is square-pyramidal with the water O atom occupying the apical position. The carboxyl-ate group bridges adjacent Cu atoms, forming an infinite zigzag chain extending parallel to [001]. The chains are linked into layers by O-H⋯O hydrogen bonds. The Cu and water O atoms lie on special positions of site symmetry 2.
