摘要

Abstract：The title complex [Cu_3(phen)_2Br_3] (1) ( phen = 1,10-phenanthroline ) has been synthesized and structurally characterized. It crystallizes in the monoclinic system, space group, C_(2/c) with a = 10.068 (5) Å , b = 14.527 (7) Å , c = 16.309 (7) Å , β= 94.333 (11)°, V = 2378.5 (19) Å^3, wR(F^2) = 0.122 and Z = 4. The diffraction data I ＞ 2σ(I) is 2032. There are two independent Cu^I ions, where Cu(1) is three-coordinated with three Br ions donor and Cu(2) is four-coordinated with two N atoms and two Br ions donor sets. The two Cu^I ions are well-separated with the nonbonding distance at 2.575(2) Å. The crystal packing is stabilized by weak intermolecular π…π interactions. In the structure, exhibits disorder of Cu(1) atom in the symmetry unit with 50% occupancies.
