Trinuclear coordination assemblies of low-spin dicyano manganese(II) ( = 1/2) and iron(II) ( = 0) phthalocyanines with manganese(II) acetylacetonate, tris(cyclopentadienyl)gadolinium(III) and neodymium(III).

The reaction of MnPc, FePc or FePcCl with KCN in the presence of cryptand[2.2.2] yielded dicyano-complexes {cryptand(K)}{M(CN)(macrocycle)}·CHCl (M = Mn and Fe, = 1 and 2) that were used for the preparation of trinuclear assemblies of the general formula {cryptand(K)}{M(CN)Pc·(ML)}·CHCl (M = Mn and Fe; = 1, 4 and 5).

Complexes of transition metal carbonyl clusters with tin(II) phthalocyanine in neutral and radical anion states: methods of synthesis, structures and properties.

Coordination of tin(II) phthalocyanine to transition metal carbonyl clusters in neutral {Sn(Pc)} or radical anion {Sn(Pc˙)} states is reported. Direct interaction of Co(CO) with {Sn(Pc)} yields a crystalline complex {Co(CO)·Sn(Pc)} (1). There is no charge transfer from the cluster to phthalocyanine in 1, which preserves the diamagnetic Pc macrocycle.
