N. Nawar et Ak. Smith, SYNTHESES OF RUTHENIUM IRIDIUM HETEROBIMETALLIC COMPLEXES USING TRIDENTATE PHOSPHINE-LIGANDS, Inorganica Chimica Acta, 227(1), 1994, pp. 79-83
Complexes of the type [Ru(C5H5)Cl{(PPh(2))(2)C=CH2}] undergo Michael-t
ype addition with a diphenylphosphine and the products can be used for
further syntheses of heterobimetallic complexes. The uncoordinated ph
osphine group of [Ru(C5H5)Cl{(PPh(2))(2)CHCH(2)PPh(2)}] (1) reacts wit
h Ir-4(CO)(12) to give mono-, di- and tri-substituted heterobimetallic
cluster complexes 2, 3 and 4, respectively.
