Synthesis and Crystal Structure of Binuclear Copper （Ⅱ） Complex Containing （Dimethylaminomethyl）ferrocene

1 INTRODUCTION Transition metal complexes with ferrocene are of considerable interest in the past fifty years because of their novel structures and special properties1, 2]. The chemistry of ferrocene and its derivatives has become richer and richer in the last decade. Many complexes containing ferrocenyl have been synthesized and characterized3～5]. Recently we have reported the synthesis and crystal structure of dibromo1,1?bis(diphenylphosphino)- ferrocene]cadmium (Ⅱ)6]. Herein we…

Synthesis and Crystal Structure of Binuclear Copper(Ⅱ)Complex Containing (Dimethylaminomethyl)ferrocene

A binuclear complex including ferrocenyl, Cu2{Fe(C5H5)C5H4CH2N(CH3)2]}2 (CH3COO)4, was synthesized and characterized by X-ray diffraction. The title complex crystallizes in triclinic, space group P with a = 8.2779(8), b = 9.4830(8), c = 12.262(1) ? = 81.079(5), b = 80.620(4), g = 78.960(4), V = 924.4(1) 3, Z = 1, C34H46Cu2Fe2N2O8, Mr = 849.51, Dc = 1.526 g/cm3, l(MoK) = 0.71073 ? ?= 1.954 mm-1, F(000) = 438, R = 0.0297 and wR = 0.0901. Both cyclopentadienyl rings in each dmaf (dmaf = (dimethylaminomethyl)ferrocene, Fe(C5H5)- C5H4CH2N(CH3)2]) have an eclipsed conformation. The binuclear molecule has a crystallographic centrosymmetry; four acetates and two Cu atoms form a cage structure with the distance between two neighboring Cu atoms of 2.655(1) .
