Three phenanthroline-metal complexes with topologically similar but geometrically different conformations

The structures of three related complexes of general formula M(pds)(nab)2 [pds is the peroxodisulfate anion and nab is an nitrogen-containing aromatic base], viz. bis(2,9-dimethyl-1,10-phenanthroline-κ2 N,N′)(peroxodisulfato-κ2 O,O′)cadmium, [Cd(S2O8)(C14H12N2)2], (V), bis(3,4,7,8-tetramethy-1,10-ph...

The main difference resides in the fact that the first two complexes are bisected by a crystallographic twofold axis, thus providing a symmetrical environment to the cation, while in the third one this symmetry is disrupted into a clearly unsymmetrical disposition, probably by way of an unusually strong intramolecular C - H⋯O hydrogen bond. The situation is compared with similar interactions in the literature. The structure of (V) is based on a redetermination in the correct space group C2/c of the structure originally described in the Cc space group [Harvey et al. (2001). Aust. J.
