The complex [Cu(phen)2py](ClO4)2 was obtained by the reaction of 1,10-phenanthroline with Cu(C1O4)2·6H2O in water and by recrystallization from pyridine. A single-crystal X-ray study shows that the complex is a square pyramidal arrangement of five nitrogen atoms from the two 1,10-phenanthroline ligands and one pyridine ligand, respectively.The compound is orthorhombic, C29H21N5C12O8Cu, Mr = 701.958, with space group Pbcn,α = 29.9593(3), b = 16.1240(3), c = 11.9183(6)A, V= 5757.3(3)A3, Z = 8, Dc= 1.409g/cm3,μ =1.121 mm-1, F(000) = 2465, R = 0.0539, Rw = 0.1380 for 4293 reflections with I＞2 σ(I). The bond lengths of Cu(1)-N(1), Cu(1)-N(2), Cu(1)-N(3) and Cu(1)-N(4) are 2.223(3),2.017(3), 2.013(3) and 2.038(3) A, respectively. The distance from copper to pyridine N(5) is 2.012(3) A. The angles N(2)-Cu(1)-N(3) and N(4)-Cu(1)-N(5) are 176.1(1)°and 160.9(1)°,respectively. The angles between axial position nitrogen atom N(1) and four square position nitrogen atoms N(2), N(3), N(4), N(5) are 79.3(1), 98.3(1), (1),108.4(1)°,respectively.
