摘要： The copper(Ⅱ) complex, [Cu(oxpn)Cu(tmen)2](ClO4)2was 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 P1, 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 Jvalue of -740. 40 cm-1.
