Eh. Wong, COORDINATION CHEMISTRY OF 8-MEMBERED POLYPHOSPHORUS HETEROCYCLES, Comments on modern chemistry. Part A, Comments on inorganic chemistry, 18(5-6), 1996, pp. 283-304
The coordination and reaction chemistry of eight-membered polyphosphor
us heterocycles is outlined with particular focus on a versatile tetra
phosphoxane P4O4 ring system. This ligand's coordination modes include
s an exo-ditopic form which has been used to prepare a mixed-valent fa
mily of heterobimetallic complexes with conserved cage structures suit
able for the study of metal-metal interactions.
