Coordination/organometallic polymers based on diphosphine and diisocyanide ligands

This paper reviews various coordination/organometallic polymers in which the metal atoms are incorporated in the backbone using diphosphine and diisocyanide ligands. Such ligands includes diphosphines of the type bis(diphenylphosphino)alkane where alkane is (CH2)(m) with in = 1, 3-6, bis(diphenylphosphino)acetylene (dpa), and bis(dimethyl-phosphino)methane (dmpm), and diisocyanides such as 1,8-diiso-cyano-p-menthane (dmb) and p-diisocyanotetramethylbenzene (ditmb). The metal fragments are monocations such as Cu+, Ag+, and Au+, dinuclear species such as Pd-2(dmb)(2)(2+), Pd-2(dppm)(2)(2+), M-2(dmpm)(3)(2+) (M = Cu, Ag), and clusters such as M-4(dmb)(4)(2+) (M = Pd, Pt).
