This paper reports a complex which has been synthesized by introducing the IMpPy to the [ Cu (oxpn) ] system. Its structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P2 ( 1 )/c , with a = 13. 935 (5) , b = 12.54(4) ,c = 13. 894(5)nm ,β = 119. 023 ,V =2 123. 1(2)nm,Mr =998.82,Z = 2,De-1. 562 g/cm3. The structure was solved by direct methods, R1 = 0. 0331,wR = 0.0880. There are two copper( Ⅱ ) atoms in the title com...
