摘　　要：The copper( Ⅱ ) complex, [Cu(oxpn)Cu(tmen)2](ClO4)2 was synthesized, where oxpn is N, N' -bis ( 3-aminopropyl) oxamido and tmen is N, N, N' N' -tetram-ethylethylenediamine. The crystal is triclinic, space group P 1, a=1-2349(2), b = 1.3093(2), c=1. 3855(2) nm, α=61-88(1), β=69.49(1), γ=57.91(1)°? V = 1. 6589 nm3, Z = 2. Both copper( Ⅱ ) ions are in a square pyramidal coordination environment , and linked by oxamido bridge. The distance between them is 0. 526 nm. Variable temperature (4. 2-300 K) magnetic susceptibility data for this complex show that there exists a relatively large antiferromagnetic exchange interaction between the two copper( Ⅱ ) ions with a J value of-740. 40 cm-1.The copper( Ⅱ ) complex, [Cu(oxpn)Cu(tmen)2](ClO4)2 was synthesized, where oxpn is N, N' -bis ( 3-aminopropyl) oxamido and tmen is N, N, N' N' -tetram-ethylethylenediamine.
