The nacnac Cu(I) compound [LCu(MeCN)] (2) (L = [{N(C6H3Me2-2,6)C(Me)}(2)CH](-)) was reacted with complexes containing aromatic cyclo-E-5 ([Cp*Fe(eta(5)-E-5)], E = P (1a), As (1b), Cp* = eta(5)-C5Me5), cyclo-P-4 ([Cp'''Co(eta(4)-P-4)] (3), Cp''' = eta(5)-(C5H2Bu3)-Bu-t) and cyclo-E-3 ligands ([Cp'''Ni(eta(3)-E-3)], E = P (4a), As (4b)) yielding the heterometallic complexes [(Cp*Fe)(mu,eta(5:2)-E-5)(LCu)] (E = P (5a), As (5b)), [(Cp*Fe)(mu(3),eta(5:2:1)-E-5)(LCu)(2)] (E = P (6a), As (6b)), [(Cp'''Co)(mu,eta(4:2)-P-4)(LCu)] (7), [(Cp'''Co)(mu(3),eta(4:2:1)-P-4)(LCu)(2)] (8), and [(Cp'''Ni)(mu,eta(3:2)-E-3)(LCu)] (E = P (9a), As (9b)). These complexes are rare examples of the coordination of a group 11 metal to aromatic cyclo-E-n (E = P, As; n = 3-5) ligands. All products were comprehensively characterized by crystallographic and spectroscopic methods. Their dynamic behavior in solution was studied by VT (variable-temperature) NMR spectroscopy, and their electronic structures were elucidated by DFT calculations.
