Two mononuclear tetrachlorocatecholate complexes, chlorotri(pyridine-N)[3,4,5,6-tetrachloro-1,2-benzenediolato(2−)-O,O']indium, [InCl(1,2-O2C6Cl4)(py)3], (1), and chloro(1,10-phenanthroline-N,N')(pyridine-N)[3,4,5,6-tetrachloro-1,2-benzenediolato(2−)-O,O']gallium, [GaCl(1,2-O2C6Cl4)(py)(phen)], (2) (py is pyridine, C5H5N, and phen is 1,10-phenanthroline, C12H8N2), have been structurally characterized as solvates, (1) as its bis(diethyl ether) solvate and (2) as its 3.5-pyridine solvate. Both (1) and (2) contain octahedrally coordinated metals but with the nitrogen donor ligands in a mer arrangement in (1) and a fac arrangement in (2). Stabilization by intramolecular CH
O and CHCl interactions is evident, and, together with steric considerations, is likely to promote the observed configurations. Compound (1) shows an interesting packing arrangement of infinite planar sheets held together by short ClCl contacts.
