摘要：
The reaction between [Rh(H2O)(6)](ClO4)(3) and the monoanion Hdopn(-) (H(2)dopn = bis(diacetylmonoxime-imino)propane 1,3=3,9-dimethyl-4,8-diazaundeca-3,8-diene-2,10-dione dioxime) afforded a new dimeric rhodium(II) compound of formula [Rh(Hdopn)(H2O)](2)(ClO4)(2). H2O (1). Treatment of methanolic solution of 1 with NaX (X = Cl-, Br-, I-) results in the replacement of water with halides in 1, leading to the formation of [Rh(Hdopn)X]2 rhodium(II) dimers. The X-ray crystal structure of [Rh(Hdopn)Cl](2)(.)0.5H(2)O (2) was determined showing a [Rh(II)-Rh(II)] core. Upon the reaction of 1 with NaI carried out in air, [Rh(Hdopn)(1)21 (3) was isolated and characterized by a single-crystal X-ray diffraction analysis. (C) 2003 Elsevier B.V. All rights reserved.
