چکیده
Biphenyl-4,4'-dicarb-oxy-lic acid was recrystallized from N,N-dimethyl-formamide (DMF) yielding the title compound, C(14)H(10)O(4)·2C(3)H(7)NO. The acid mol-ecules are located on crystallographic centres of inversion and are hydrogen bonded to DMF mol-ecules. These hydrogen-bonded units form infinite chains although there is no inter-action between the methyl groups of neighboring DMF mol-ecules.

In the crystal struture of the title compound, C(16)H(14)O(6)·C(3)H(7)NO, the two crystallographically independent benzene rings are coplanar [dihedral angle = 1.00 (2)°]. The crystal structure is stabilized by O-H⋯O hydrogen bonds between the diacid and the solvate dimethylformamide mol-ecule, resulting in the formation of a zigzag chain structure extending parallel to [001].

In the title compound, [RuCl(C(15)H(11)N(3))(C(12)H(8)N(2)O(4))]ClO(4)·C(2)H(5)OH·H(2)O, the geometry of the ClN(5) coordination set around the Ru(II) atom is close to octa-hedral, but distorted on account of the limited bite angles of the polypyridyl ligands. The complexes are linked by O-H⋯O hydrogen bonds between the carboxyl groups and the crystal lattice water mol-ecules into chains along ...

In the title compound, 3C(10)H(8)N(2)·4C(7)H(5)NO(4), the asymmetric unit contains two mol-ecules of pyridine-3,5-dicarb-oxy-lic acid and one mol-ecule of 4,4'-bipyridine in general positions together with one mol-ecule of 4,4'-bipyridine lying across a centre of inversion, thus giving a 4:3 molar ratio of pyridine-3,5-dicarb-oxy-lic acid to 4,4'-bipyridine. The dihedral angle between the bipyr...

The title compound, {[NiCl(2)(C(5)H(6)N(2))(C(3)H(7)NO)]·C(3)H(7)NO}(n), is a two-dimensional polymer in which the Ni(II) atom is coordinated by two N atoms from two 3-amino-pyridine ligands, one O atom from a dimethyl-formamide (DMF) group, one terminal Cl and two bridging Cl atoms in a distorted octa-hedral geometry. The Ni(II) atoms are bridged by the 3-amino-pyridine ligands [Ni⋯N = 6.7048 ...

The reaction of nickel salts and 4,4'-bipyridine with 2,2'-bi-imidazole (H(2)biim) yielded the title complex, [Ni(C(6)H(6)N(4))(3)](NO(3))(2)·C(3)H(7)NO. The Ni(II) atom is chelated by three H(2)biim ligands in a distorted octa-hedral coordination geometry. The two nitrate anions and one dimethyl-formamide (DMF) mol-ecule are not coordinated. The compound has a three-dimensional structure, form...
