摘要：

Two dinuclear molecule-bridged Cu(I) complexes, (mu-bpym)[Cu(PPh3)Cl](2) (1). [(mu-bpym)(CuL)(2)] (ClO4)(2)center dot(CH3CN)(2)(H2O) (2) (bpym = 22'-bipyrimidine, L= (R)-(+)-2,2'-bis(diphenylphospho)-1,1'-dinaphthalene) have been synthesized and characterized. The molecular structures of the two new dinuclear compounds exhibit bridging of two copper(I) centers by the symmetrically bis-chelating bpym ligand. Intriguingly, compound 1 features a remarkable "intramolecular organic sandwich" configuration where the central 2,2'-bipyrimidine bridging ligand interacts in pi/pi/pi fashion with two phenyl rings from the coligands above and below the central plane, while chiral compound 2 exhibits second-order nonlinear optical effect and temperature-dependent luminescence. Upon decreasing the temperature from 298 to 10K, compound 2 shows a red light emission. (C) 2011 Elsevier B.V. All rights reserved.
