✦ Synopsis

The crystal structure of [Pb(sac) 2 ophen(H 2 O) 2 ] (sac = saccharinate anion; ophen = 1,10-phenanthroline) has been solved by single X-ray diffractometry. It crystallizes in the monoclinic space group C2/c with Z = 4. The Pb II atom presents the coordination number eight with unusual coordination of the ligand atoms between square-antiprism and dodecahedron. The saccharinate anion acts as a bidentate ligand. The i. r. spectrum of the complex has been analyzed in detail and assigned on the basis of the structural peculiarities.
