Catena-Poly[[[aqua-(5-nitro-benzene-1,2,3-tricarboxyl-ato-?O)copper(II)]-di-?-aqua-[diaqua-sodium]-di-?-aqua] tetra-hydrate].

ABSTRACT: In the heteronuclear coordination polymer, {[CuNa(C(9)H(2)NO(8))(H(2)O)(7)]·4H(2)O}(n), the Cu(II) atom is coordinated by six O atoms from five water mol-ecules and one 5-nitro-benzene-1,2,3-tricarboxyl-ate ligand in a slightly distorted octa-hedral geometry. The Na(+) cation is surrounded by six water mol-ecules in an irregular trigonal-prismatic geometry. The Cu and Na atoms are connected by water bridges, forming an infinite chain. O-H?O hydrogen bonds involving the coordinated and uncoordinated water mol-ecules connect the chains into a three-dimensional network.

Project description:In the title compound, {[Zn(3)(C(9)H(3)O(6))(2)(H(2)O)(8)]·4H(2)O}(n), there are two crystallographically independent Zn(II) ions. One presents a trigonal-bipyramidal coordination geometry defined by five O atoms [three from two carboxyl-ate groups of two benzene-1,3,5-tricarboxyl-ate (BTC) ligands and the other two deriving from three water mol-ecules], while the other lies on an inversion centre and exists in a slightly distorted octa-hedral coordination geometry defined by six O atoms (two from two carboxyl-ate groups of two BTC ligands and the others from four water mol-ecules). A three-dimensional framework is further strengthened via O-H?O hydrogen-bonding inter-actons.

Poly[[aqua-?(6)-benzene-1,2,3-tricarboxyl-ato-?(3)-hydroxido-dizinc] hemihydrate].

Project description:In the title compound, {[Zn(2)(C(9)H(3)O(6))(OH)(H(2)O)]·0.5H(2)O}(n), there are three independent Zn(II) atoms present; two are located on special positions, viz a twofold rotation axis and an inversion centre, and the third is located in a general position. The Zn(II) atom on the inversion centre is six-coordinated by four O atoms from four different benzene-1,2,3-tricarboxyl-ate anions and two OH(-) anions. The Zn(II) atom located on a twofold axis is four coordinated by two O atoms from two different benzene-1,2,3-tricarboxyl-ate anions and two OH(-) anions. The third Zn(II) atom, located in a general position, is five coordinated by three O atoms from three different benzene-1,2,3-tricarboxyl-ate anions, one OH(-) anion and one water mol-ecule. Each benzene-1,2,3-tricarboxyl-ate anion bridges six Zn(II) atoms, and the OH(-) anion bridges three Zn(II) atoms, resulting in the formation of a three-dimensional framework. A series of O-H?O hydrogen bonds involving the benzene-1,2,3-tricarboxyl-ate anions, the OH(-) anion and the coordinating and the two water solvent mol-ecules further stablize the crystal structure. The two solvent water molecules show occupancies of 0.5 and 0.25.

Project description:In the asymmetric unit of title coordination polymer, {(C(16)H(36)N)[Zn(3)(C(9)H(3)O(6))(2)(OH)]·0.25H(2)O}(n), there are three independent Zn(2+) cations, two benzene-1,3,5-tricarboxyl-ate ligands and a ?(3)-bridging hydroxide group, together with a tetra-n-butyl-ammonium counter-cation and a partially occupied water molecule of solvation (occupancy 0.25). Each Zn ion is coordinated by three carboxyl-ate O atoms and one O atom from the bridging hydroxide ion, displaying a slightly distorted tetra-hedral stereochemistry [overall Zn-O range = 1.875?(3)-1.987?(2)?Å]. An intra-molecular hydrogen bond involving the hydroxide H atom and a carboxyl-ate O-atom acceptor is also present in the complex unit. The bridging benzene-1,3,5-tricarboxyl-ate anions generate a three-dimensional framework structure.

Project description:In the title compound, {[Nd(C(8)H(3)NO(6))(C(8)H(4)NO(6))(H(2)O)(2)]·2.5H(2)O}(n), the Nd(II) ion is nine-coordinated by seven O atoms from five carboxyl-ate groups and two water mol-ecules. The [Nd(C(8)H(3)NO(6))(H(2)O)(2)](2+) units are bridged by 5-nitro-isophthalate dianions, forming polymeric sheets parallel to the ab plane. The polymeric sheets are linked into a three-dimensional network by O-H?O and C-H?O hydrogen bonds, and ?-? inter-actions [centroid-centroid distance = 3.5533?(11)?Å]. The 5-nitro-isophthalate(1-) anion is disordered over three positions with an occupancy ratio of 0.68:0.23:0.09. Two of the uncoordinated water mol-ecules are disordered over two positions, with occupancy ratios of 0.722?(15):0.278?(15) and 0.279?(6):0.221?(6), respectively.

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

catena-Poly[[cobalt(II)-?-aqua-di-?-butano-ato-?O:O';?O:O] 0.7-hydrate].

Project description:In the title coordination polymer, {[Co(C(3)H(7)COO)(2)(H(2)O)]·0.7H(2)O}(n), the Co(2+) cation is coordinated by four bridging butano-ate anions and two bridging water mol-ecules in a severely distorted octa-hedral geometry. The Co(2+) cations are linked by means of bridging ligands into polymeric chains along [010]. These chains are further connected to each other through hydrogen bonds involving partially occupied disordered water mol-ecules; thus, sheets parallel to (001) are formed. One of the positions of disordered water O atom lies on a twofold axis. Two atoms of the aliphatic chain of one of the butanoate anions are disordered over two positions each.

Poly[[nona-aqua-bis-(?-5-hy-droxy-benzene-1,3-di-carboxyl-ato)(5-hy-droxy-benzene-1,3-di-carboxyl-ato)dicerium(III)] hexa-hydrate].

Project description:In the title coordination polymer, {[Ce2(C8H4O5)3(H2O)9]·6H2O} n , the asymmetric unit is formed by two Ce(III) atoms, three 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands, nine coordinating water mol-ecules and six water mol-ecules of crystallization. The two Ce(III) atoms are bridged by 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands acting in a bis-bidentate coordination mode, generating infinite chains along [101]. Both independent metal atoms are nine-coordinated, one by four O atoms from the carboxyl-ate groups of two bridging 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands and five O atoms from water mol-ecules, generating a tricapped trigonal-prismatic geometry. The coordination around the second Ce(III) atom is similar, except that one of the water mol-ecules is replaced by an O atom from an additional 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligand acting in a monodentate coordination mode and forming a capped square-anti-prismatic geometry.

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.

Diguanidinium bis-(μ-2-hydroxy-propane-1,2,3-tricarboxyl-ato)bis-[diaqua-zincate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, (CH(6)N(3))(2)[Zn(2)(C(6)H(5)O(7))(2)(H(2)O)(2)]·2H(2)O, contains one-half of a centrosymmetric dizinc(II) complex anion, one guanidinium cation and one water mol-ecule. Each Zn(II) ion is hexa-coordinated by two citrate anions, one in a bidentate fashion and the second monodentate, and two water mol-ecules in a distorted octa-hedral geometry. Intra-molecular O-H⋯O hydrogen bonds add further stability to the mol-ecular structure. In the crystal structure, mol-ecules are linked into a three-dimensional framework by inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds.
