Abstract

Reaction of a new large-bite P,N-ligand, 2-(N-diphenylphosphinomethyl-N-benzyl)aminopyridine (1) with (COD)PtCl2 and (COD)Pt(C[triple bond, length as m-dash]CPh)2 give cis-(L)2PtCl2 (2) and trans-(L)2Pt(C[triple bond, length as m-dash]CPh)2 (3), respectively. Complex 3 reacted with M(I) (M = Cu, Ag) perchlorate using its pyridyl and alkynyl groups to afford a novel type of mixed-metal macrocyclic complexes PtM2(L)2(C[triple bond, length as m-dash]CPh)2(ClO4)2 (M = Cu, 4; M = Ag, 5). Complex 4 can be converted to the solvated complexes Pt[Cu(solvent)]2(μ-L)2(C[triple bond, length as m-dash]CPh)2(ClO4)2 (solvent = H2O, 4; CH3CN, 4″) by recrystallization of 4 in the corresponding solvents. The crystal structures of complexes 2, 3, 4 and 4″·CH2Cl2 and luminescence properties of 3, 4 and 5 have been determined.
