Abstract

In this paper, we report the crystal structures of a bimetallic trans-[cis-Mo(CO)4(PPh2NHCH2CH2N=CH(o-C6H4O)]]Cu Complex (monoclinic space group P2/c), the cis-Mo(CO)4(PPh2Cl)2 starting material, (monoclinic space group C2/c) and the two reaction intermediates cis-Mo(CO)4(PPh2NHCH2CH2N=CH(o-C6H4OH)2 (orthorhombic space group P2(1)2(1)2). The dihedral angle between the o-salicylaldiminato groups in the bimetallic complex (36.32(18)°) is considerable large than that in the previously reported trans-[cis-Mo(CO)4-[PPh2NHCH2CH2N=CH(o-C6H4O)]2]Ni complex (12.6°) demonstrating that the coordination preferences of the metal dications have significant effects on the conformations of the bimetallic complexes. The orientations of the phosphinamide ligands bimetallic complex are quite different than are those in the intermediates due to the steric restraints imposed by chelation to the Cu2+.
