Abstract top

The 4,4'-bipyridine heterocycle in the polymeric title compound, [Cd(C16H13O3)2(C10H8N2)(H2O)]n, links adjacent Cd(II) ions into a chain running along the c axis. The Cd atom, which lies on a twofold rotation axis, is chelated by the carboxylate unit and exists in a seven-coordinate pentagonal-bipyramidal geometry. The apical sites are occupied by N atoms. The water molecule also lies on the twofold rotation axis. The methyl substituent of the propanoate group is disordered over two positions in a 1:1 ratio. O-H...O hydrogen bonding between water molecules and adjacent carboxylate O atoms is observed.

Comment top

The drug, 2-(3-benzoylphenyl)propanoic acid (Kétoprofène) (Briard & Rossi, 1990), forms a small number of metal derivatives; in the cobalt(II) and nickel(II) derivatives, the carboxyl unit binds in a unidentate manner to the water-coordinated metal atoms (Zhang et al., 2007a, 2007b). In the title cadmium–4,4'-bipyridine adduct (Scheme I), the N-heterocycle links adjacent formula units into a chain running along the c-axis of the monoclinic unit cell. The cadmium atom, which lies on a twofold rotation axis, is chelated by the carboxyl unit and it exists in seven-coordinate pentagonal bipyramidal geometry. The apical sites are occupied by N atoms. The water molecule also lies on the twofold rotation axis (Fig. 1). The methyl subsituent of the carboxylate is disordered over two positions in a 1:1 ratio.

Experimental top

Cadmium nitrate (1 mmol) and 4,4'-bipyridine (1 mmol) were dissolved in ethanol (50 ml); the solution was added to an aqueous solution (50 ml) of 2-(3-benzoylphenyl)propanoic acid (2 mmol). The pH was adjusted to 7 by the addition of aqueous sodium hydroxide. The solution was filtered and then set aside for the growth of crystal.

Refinement top

The methyl substitutent in the carboxylate is disordered over two positions; as the occupancy refined to nearly 50%, the occupancy was then fixed as 50:50. The pair of Cmethine–Cmethyl distances were restained to within 0.01 Å of each other.

All hydrogen atoms were generated geometrically (C–H 0.93 to 0.98, O–H 0.84; U 1.2 to 1.5 Ueq of the arrier atom).
