4,4'-Bipyridine-pyridine-3,5-dicarb-oxy-lic acid (3/4).

ABSTRACT: 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 bipyridine rings on general positions is 21.2?(2)°. These mol-ecular units are linked by O-H?N hydrogen bonds forming an extended two-dimensional framework in the crystal.

Project description:In the title co-crystal, C(10)H(8)N(2)·C(8)H(7)NO(4)S, the formate group is coplanar with the pyridyl ring of the acid [dihedral angle = 6.2?(7)°], while the carb-oxy-methyl-sulfanyl group makes a C-S-C-C torsion angle of 70.2?(1)° with the pyridine ring. The dihedral angle between the pyridyl rings of the 4,4'-bipyridine mol-ecule is 27.4?(1)°. The acid and the 4,4'-bipyridine mol-ecules are involved in hydrogen bonding via carb-oxy-lic O and pyridyl N atoms. The structure is further consolidated by inter-molecular C-H?O hydrogen bonds, generating a three-dimensional network.

Biphenyl-4,4'-dicarb-oxy-lic acid N,N-dimethyl-formamide monosolvate.

Project description: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.

4,4'-Bipyridine-cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid (1/1).

Project description:In the title 1:1 adduct, C(10)H(8)N(2)·C(10)H(12)O(8), the dihedral angle between the pyridine rings in the 4,4-bipyridine molecule is 8.33 (13)°. In the crystal, the cyclo-hexane-1,2,4,5-tetra-carb-oxy-lic acid mol-ecules inter-act with each other through inter-molecular O-H⋯O hydrogen bonds, forming an infinite chain along the a axis, which is further linked perpendicularly by O-H⋯N hydrogen bonds involving bipyridine, resulting in a supra-molecular corrugated sheet parallel to the (110) plane.

(2,2'-Bipyridine-4,4'-dicarb-oxy-lic acid-?N,N')chlorido(2,2':6',2''-terpyridyl-?N,N',N'')ruthenium(II) perchlorate ethanol monosolvate monohydrate.

Project description: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 [110]. Face-to-face stacking inter-actions are formed between terpyridine ligands, with inter-planar separations of 3.66?(1) and 3.42?(1)?Å, and between bipyridine-4,4'-dicarb-oxy-lic acid ligands, with inter-planar separations of 3.65?(1) and 3.72?(1)?Å. Three O atoms of the perchlorate ion are each disordered equally over two positions. The hy-droxy group of the ethanol mol-ecule is also disordered over two sites with refined occupancies of 0.794?(9) and 0.206?(9).
