摘　　要：Dicyanide building block cis-Fe（phen）2（CN）2 and [MnⅢ（salen）]（ClO4） have been used to design and synthesize a cyanide-bridged complex, resulting in a heterobimetallic one-dimensional（1D） zigzag chain complex 1, [cis-Fe（phen）2（CN）2Mn（salen）]（PF6）（phen =1,10-phenanthroline, salen=N,N-ethylenebis-（salicylideneaminato） dianion）. Single-crystal X-ray diffraction analysis shows complex 1 crystallizes in the monoclinic P2（1/c） space group and the asymmetric unit contains one [-NC-Fe（phen）2（μ-CN）-MnⅢ-（salen）-]＋ cation and one PF6- anion. In the cationic structure of 1, each FeⅡ（phen）2（CN）2 connects two [MnⅢ（salen）]＋ with two cyanide groups in a cis-conformation, and in turn each [MnⅢ（salen）]＋ unit links two FeⅡ（phen）2（CN）2 building blocks in a trans-conformation, resulting in a 1D [-NC-FeⅡ-CN-MnⅢ-]n chain. Furthermore, the electronic absorption spectra and electrochemical and magnetic properties of complex 1 have also been studied.Dicyanide building block cis-Fe（phen）2（CN）2 and [MnⅢ（salen）]（ClO4） have been used to design and synthesize a cyanide-bridged complex, resulting in a heterobimetallic one-dimensional（1D） zigzag chain complex 1, [cis-Fe（phen）2（CN）2Mn（salen）]（PF6）（phen =1,10-phenanthroline, salen=N,N-ethylenebis-（salicylideneaminato） dianion）.
