Novel isomorphous tetranuclear complexes, [(dppf)Cu(mu(3),eta(2 : 2 : 2)-E-2{CpMo(CO)(2)}(2)]BF4 [E=P (1), As (4), Sb (5), (dppf=1,1 '-bis-(diphenylphosphino)-ferrocene)] and [(dppf)Cu(mu(3),eta(2 : 2 : 2)-PE{CpMo(CO)(2)}(2)]BF4 [E=As (2), Sb(3)] were synthesized from the reactions between [(dppf)Cu(MeCN)(2)][BF4] and tetrahedral molybdenum complexes containing unsubstituted homo- and hetero-diatomic group-15 elements [(mu,eta(2 : 2)-E-2{CpMo(CO)(2)}(2)] [E=P (A), As (D), Sb (E)] and [(mu,eta(2 : 2)-PE{CpMo(CO)(2)}(2)] [E=As (B), Sb (C)], respectively. In all these products, the {Mo2E2} or {Mo2PE} moieties coordinate the Cu(I) center via a rare side-on eta(2)-coordination mode. The X-ray structure analyses of [(dppf)Cu(mu(3),eta(2 : 2 : 1)-PSb{CpMo(CO)(2)}(2)][BF4] demonstrate, for the first time, the utilization of an eta(1)-coordination mode for the ligand complex C to coordinate to the Cu(I) center. All the products were characterized by X-ray crystallography, NMR and IR spectroscopy, mass spectrometry and elemental analysis. Electrochemical studies also revealed the formation of 1-5, and, further, to understand the structure and bonding of the products, theoretical calculations using density functional theory (DFT) were conducted.
