摘要：
The new complex Cu[L1]Cr2O7has been synthesised with the N,N′-bis(2-pyridylmethylene) butane-1,4-diamine Schiff base L1, [NC5H4CH=N(CH2) 4N=CHC5H4N], and characterised with elemental analyses and different spectroscopic and electrochemical studies. The structure of the new complex has been established by single crystal X-ray diffraction. The complex crystallises in the monoclinic system with space group P21/c having cell parameters a = 14.7(5), b = 9.22(2), c = 16.2(5) Å, β= 116.9(1)°, and Z = 4. The Cr2O72- unit is bonded through one terminal oxygen donor end to the central Cu(II) chelated by the Schiff base ligand. © 2007 Verlag der Zeitschrift für Naturforschung.
