摘要
Dibenzoyl peroxide undergoes oxidative addition with metallic copper powder and 2, 2’-bipyridine in a mixed solvent （methanol and tetrahydrofuran ） to afford copper（Ⅱ） complex [Cu（2, 2’-bipy） （C<sub>6</sub>H<sub>5</sub>COO）<sub>2</sub>]· H<sub>2</sub>O. The structure of the cornplex was solved by direct methods and refined by block-diagonal and full-ma-trix least-squares method to a final R of 0. 055 for 2654 independent reflections of I 】3σ（I）. Crystals are monoclinic,space group P2<sub>1</sub>/c , Mr= 479. 78 with cell parameters a= 6. 986（7） , b= 18. 833（1）, c= 17. 021（3）, β=97. 96（1）°, Z=4, Dc=1. 437g. cm￣（-3）, V= 2218. 1. Each copper ion is coordinated by the oxygen atoms of two benzoato groups and the nitrogen atoms of 2. 2’-bipyridine in a planar square geometry.
