Dinuclear Rh(II) complexes with one polypyridyl ligand, structure, properties and antitumor activity
摘要:
Rhodium(II) complexes [Rh(2)(mu-OAc)(2)(OAc)(bpy)(H(2)O)(2)]PF(6) (1), [Rh(2)(mu-OAc)(2)(OAc)(phen)(H(2)O)(2)](PF(6)).H(2)O (2), [Rh(2)(mu-OOCCH(3))(3)(OOCCH(3))(phen)] (3) and [Rh(2)(mu-O(2)CCH(3))(3)(O(2)CCH(3))(Ph(2)phen)] (4) (Ph(2)phen = 4,7-diphenyl-1,10-phenanthroline) have been synthesized and characterized by means of NMR, IR and UV-Vis spectroscopic methods. X-ray structure of complex 4.1.5(CH(3)COCH(3)) has been determined and its geometry and electronic structure has been elucidated using OPBE and B3LYP DFTmethods. The compounds are active cytostatic agents against tumor cells. (C) 2010 Elsevier B.V. All rights reserved.
