|
摘要
Tricyanide building block K[Ru(ttpy)(CN)_3] and [Mn~Ⅲ(salen)](ClO_4) have been used to design and synthesize a heterobimetallic one-dimensional(1D) zigzag chain complex 1,[Ru~Ⅱ(ttpy)(CN)_3 Mn~Ⅲ(salen)](ttpy = 4?-(p-tolyl)-2,2?:6?,2??-terpyridine, salen = N,N?-ethylenebis-(salicylideneaminato)dianion). Single-crystal X-ray diffraction analysis shows complex 1 crystallizes in orthorhombic Pbca space group and the asymmetric unit of 1 contains one[-NC-Ru~Ⅱ(ttpy)(CN)(m-CN)-Mn ~Ⅲ-(salen)-] molecule. In the structure of 1, each [Ru ~Ⅱ(ttpy)(CN)_3]~-connects two [Mn~Ⅲ(salen)]~+ with two cyanide groups in a cis-conformation, and in turn each[Mn~Ⅲ(salen)]~+ unit links two [Ru~Ⅱ(ttpy)(CN)_3]~-building blocks in a trans-conformation, resulting in a 1D [-NC-Ru~Ⅱ-CN-Mn~Ⅲ-]_n chain. Furthermore, the electronic absorption spectra and luminescence spectroscopy of complex 1 have also been studied.
