Structural investigations of metal–nitrate complexes. Part VII. Crystal and molecular structure of aquodinitratobis(quinoline)cadmium(II)

Abstract

The structure of the title compound has been determined by three-dimensional X-ray analysis from diffractometer data. Crystals are monoclinic, space group P2₁/c, with Z= 4 in a unit cell of dimensions a= 11·018 ± 0·005, b= 8·585 ± 0·005, c= 23·756 ± 0·009 Å, β= 91·07 ±0·2°. The structure was solved by the heavy-atom method and refined by least-squares calculations to a final R of 0·08 for 3697 independent reflexions. The molecule is a seven-co-ordinate monomer with non-equivalent bidentate nitrate groups. The bonding environment of the cadmium is a distorted pentagonal bipyramid, and there is a complex system of intermolecular hydrogen bonding.
