Crystal structure of bis-[(1,8-naphthyridine)mercury(I)] diperchlorate

Abstract

The crystal structure of the title compound has been determined from X-ray diffractometer data by the heavy-atom method and refined by full-matrix least-squares to R 0·08 for 1033 observed reflections. Crystals are monoclinic, space group P2₁/n, a= 18·639(3), b= 5·164(1), c= 11·224(1)Å, β= 105·95(1)°, with two of the dimeric species in the cell. Hg–Hg is 2·511(1)Å; the naphthyridine ligand is essentially unidentate and coplanar with the mercury and has a very short Hg–N distance of 2·03(2)Å.
