چکیده
There are two mol-ecules with similar bond dimensions in the asymmetric unit of the title complex, [Re(C(7)H(4)NO(4))(CO)(3)(H(2)O)]. The metal centre is coordinated facially by three carbonyl groups, is chelated by a 4-carboxy-pyridine-2-carboxyl-ate ligand and is also coordinated by a water mol-ecule. O-H⋯O hydrogen bonds give rise to a three-dimensional network.

In the title coordination polymer, [AgTb(C(7)H(3)NO(4))(C(7)H(4)NO(4))(C(2)O(4))(0.5)(H(2)O)(2)](n), the Tb(III) ion is eight-coordinated by three O atoms from three different pydc (H(2)pydc = pyridine-3,5-dicarboxylic acid) ligands, one O atom from one Hpydc ligand, two O atoms from one oxalate ligand and two water mol-ecules in a distorted square-anti-prismatic geometry. The Ag(I) ion is coor...

In the title compound, [Re(C10H6NO2)(CO)3{As(C6H5)3}], the coordination environment of Re(I) is that of a distorted octa-hedron. Three coordination sites are occupied by three carbonyl groups in a facial arrangement and the remaining three sites by tri-phenyl-arsane and deprotonated quinaldic acid in As-mono- and N,O-bidentate fashions, respectively. In the crystal, the complexes are linked thr...

The neutral binuclear title complex, [Cd(2)(C(16)H(10)NO(2))(4)(C(10)H(8)N(2))(2)], is centrosymmetric, with the inversion center generating the central (μ-O)(2)Cd(2) bridge. The Cd(II) ion is in a strongly distorted CdN(2)O(5) penta-gonal-bipyramidal geometry, defined by two N atoms from one 2,2'-bipyridine ligand and five O atoms from three 2-phenyl-quinoline-4-carboxyl-ate ligands, one monod...

The title compound, [Gd(C(5)H(2)N(2)O(4))(C(5)H(3)N(2)O(4))(C(12)H(8)N(2))(2)]·2H(2)O, was obtained from a solvothermal reaction of 2,4-dihydroxy-pyrimidine-5-carboxylic acid (H(3)iso), GdCl(3)·6H(2)O and 1,10-phenanthroline (phen). The Gd(III) ion is located on a twofold rotation axis and is coordinated by four N atoms from two chelating phen ligands and four O atoms (5-carboxyl-ate and 4-oxid...

The asymmetric unit of the title compound, [Cu(C(5)H(3)O(3))(2)(C(12)H(8)N(2))(2)(H(2)O)]·0.5CH(3)OH, contains two Cu(II) complex mol-ecules and one methanol solvent mol-ecule with the metal centres in strongly distorted octahedral coordination. The coordinated water mol-ecule is involved in inter-molecular O-H⋯O hydrogen bonding, which links the complex mol-ecules into chains propagating along...
