distorted octahedral. Selected bond distances (A) are: ReO(oxide) 1.671(6), ReCl(trans to O) 2.452(3), ReCl(trans to P) 2.365(4) and 2.373(3), ReP 2.439(3) and 2.449(2). The PReP chelation angle is 69.2(1)°. Compound 3 is orthorhombic, space group Pccn, with a=34.843(5), b=8.242(2) and c=19.342(4) A. The molecular complex is roughly octahedral with the oxidized dppm ligand chelated through the
