(?-Butane-1,2,3,4-tetra-carboxyl-ato)bis-[triaqua-(1,10-phenanthroline)nickel(II)] hexa-hydrate.

ABSTRACT: The asymmetric unit of the title compound, [Ni(2)(C(8)H(6)O(8))(C(12)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains a half of the centrosymmetric dinuclear complex mol-ecule and three uncoordinated water mol-ecules. In the dinuclear mol-ecule, two Ni(II) cations are bridged by the butane-1,2,3,4-tetra-carboxyl-ate (BTC(4-)) anion. Each Ni(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, one O atom from the BTC(4-) anion and three aqua ligands in a distorted octa-hedral geometry. Inter-molecuar O-H?O hydrogen bonds and ?-? stacking inter-ations [centroid-centroid distances = 3.646?(2), 3.781?(2) and 3.642?(2)?Å] consolidate the crystal packing.

Project description:The asymmetric unit of the title Mn(II) coordination polymer, {[Mn(2)(C(8)H(6)O(8))(H(2)O)(3)]·H(2)O}(n), contains two crystallographic-ally independent Mn(II) cations, two half butane-1,2,3,4-tetra-carboxyl-ato anions, each lying on a centre of inversion, and four water mol-ecules. The Mn(II) cation has a distorted octa-hedral coordination environment. One Mn centre is coordinated by four carboxyl-ate O atoms from two different anions and two water O atoms. The other Mn centre is coordinated by five carboxyl-ate O atoms from four different anions and one water O atom. One water mol-ecule does not coordinate to a Mn centre. The crystal packing is stabilized by several O-H?O hydrogen bonds, forming a three-dimensional framework.

Poly[diammonium [(?(4)-butane-1,2,3,4-tetra-carboxyl-ato)zincate] tetra-hydrate].

Project description:In the title compound, {(NH(4))(2)[Zn(C(8)H(6)O(8))]·4H(2)O}(n), the asymmetric unit contains one ammonium cation, half of a butane-1,2,3,4-tetra-carboxyl-ate anion, one Zn(2+) cation and two water mol-ecules. The butane-1,2,3,4-tetra-carboxyl-ate ligand is located about an inversion centre at the mid-point of the central C-C bond. The Zn(2+) cation is situated on a twofold rotation axis and is surrounded by four O atoms from four symmetry-related butane-1,2,3,4-tetra-carboxyl-ate anions in a distorted tetra-hedral environment. In turn, each anion coordinates to four Zn(2+) cations. The bridging mode of the anions leads to a three-dimensional framework structure with channels extending along [110] and [010] in which the ammonium cations and the water mol-ecules are located. N-H?O and O-H?O hydrogen bonding between the cations and water mol-ecules and the uncoordinating O atoms of the carboxyl-ate groups consolidates the crystal packing.

Project description:The asymmetric unit of the title Cd(II) coordination polymer, [Cd(2)(C(8)H(6)O(8))(H(2)O)(3)](n), contains two crystallographically independent Cd(II) cations, one-half each of two independent anionic butane-1,2,3,4-tetra-carboxyl-ate units (L) and three water mol-ecules. Both anionic units lie on inversion centers. One of the Cd(II) ions is six-coordinated by four carboxyl-ate O atoms from four L anions and two water O atoms in a distorted octa-hedral coordination environment. The other Cd(II) ion is eight-coordinated by seven carboxyl-ate O atoms from four L anions and one water O atom. The anionic units bridge neighboring Cd(II) centers, forming a three-dimensional framework. O-H?O hydrogen-bonding inter-actions between the water mol-ecules and carboxyl-ate O atoms further stabilize the structure.

μ-Biphenyl-3,3',4,4'-tetra-carboxyl-ato-κO:O-bis-[triaqua-(2,2'-bipyridyl-κN,N')nickel(II)] hexa-hydrate.

Project description:The asymmetric unit of the title complex, [Ni(2)(C(16)H(6)O(8))(C(10)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains one Ni(II) atom, one 2,2'-bipyridine ligand, three coordinated water mol-ecules, one-half of a fully deprotonated biphenyl-3,3',4,4'-tetra-carboxyl-ate anion and three lattice water mol-ecules. The Ni(II) atom displays a distorted NiN(2)O(4) octa-hedral coordination formed by one carboxyl-ate O atom, three water O atoms and two N atoms of the chelating ligand. The complete biphenyl-3,3',4,4'-tetra-carboxyl-ate ligand displays inversion symmetry and links two symmetry-related Ni(II) atoms into a binuclear complex. Neighbouring complex mol-ecules are linked through O-H⋯O hydrogen bonds into a three-dimensional structure. Additional O-H⋯O hydrogen bonds between the lattice water mol-ecules help to consolidate the crystal packing.

(3-Acetyl-4-methyl-1H-pyrazol-1-ide-5-carboxyl-ato)bis-(1,10-phenanthroline)nickel(II) 3.5-hydrate.

Project description:The title compound, [Ni(C7H6N2O3)(C12H8N2)2]·3.5H2O, crystallizes as a neutral mononuclear complex with 3.5 solvent water mol-ecules. One of the water mol-ecules lies on an inversion centre, so that its H atoms are disordered over two sites. The coordination environment of Ni(II) has a slightly distorted octa-hedral geometry, which is formed by one O and five N atoms belonging to the N,O-chelating pyrazol-1-ide-5-carboxyl-ate and two N,N'-chelating phenanthroline mol-ecules. In the crystal, O-H⋯O, N-H⋯O and O-H⋯N hydrogen bonds involving the solvent water mol-ecules and pyrazole-5-carboxyl-ate ligands form layers parallel to the ab plane. These layers are linked further via weak π-π inter-actions between two adjacent phenanthroline mol-ecules, with centroid-to-centroid distances in the range 3.886 (2)-4.018 (1) Å, together with C-H⋯π contacts, forming a three-dimensional network.

Bis[1-hydroxy-ethyl-idenediphosphon-ato(1-)](1,10-phenanthroline)nickel(II) mono-hydrate.

Project description:In the mononuclear title compound, [Ni(C(2)H(6)O(7)P(2))(2)(C(12)H(8)N(2))]·H(2)O, the Ni(II) atom (site symmetry 2) is bonded to two phosphate-based O,O'-bidentate chelate ligands and one N,N'-bidentate 1,10-phenanthroline ligand, resulting in a slightly distorted cis-NiN(2)O(4) octa-hedral geometry. In the crystal structure, pairs of complexes are linked by double hydrogen bonds, forming a one-dimensional chain-like structure. Aromatic π-π stacking inter-actions [centroid-centroid separation = 3.768 (2) Å] and further hydrogen bonds generate a two-dimensional structure. The water O atom also lies on a crystallographic twofold axis.

In the cation, the metal centre is coordinated by six N atoms from three 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The [Cr(2)O(7)](2-) anion exhibits a staggered conformation. The crystal packing is stabilized by inter-molecular O-H?O hydrogen bonds and ?-? inter-actions, evidenced by short distances of 3.531?(5)?Å between the centroids of aromatic rings.

The butane-1,2,3,4-tetra-carboxyl-ate ligands lie on inversion centers and bridge Sr(II) ions, forming a three-dimensional network.

Diaqua-bis-(1,10-phenanthroline-κN,N')cadmium sulfate hexa-hydrate.

Project description:The title compound, [Cd(C(12)H(8)N(2))(2)(H(2)O)(2)]SO(4)·6H(2)O, was obtained unexpectedly during an attempt to synthesize a cadmium complex with bidentate bridging sulfate ligands via hydro-thermal synthesis. The Cd(II) metal ion is six-coordinated by two chelating 1,10-phenanthroline ligands and two water mol-ecules, resulting in a distorted octa-hedral geometry for the metal ion. The two chelating N(2)C(2) groups are almost perpendicular to each other [dihedral angle = 86.75 (2)°]. In the crystal, the [Cd(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) complex cations join with the sulfate anions through two O(water)-H⋯O(sulfate) hydrogen bonds. These ion pairs are further inter-linked into a two-dimensional supermolecular structure via additional O-H⋯O hydrogen bonds.
