Four Cyano-bridged Complex Metal Complexes {[CuPb (L1)] [FeⅢ (bpb) (CN) 2]} 2 · (ClO4) 2.2H2O.2CH3CN (1), {[CuPb 2- [FeⅡ (CN) 6] (H2O) 2} · 10H2O (2), {[Cu2 (L2)] [FeⅢ (bpb) (CN) 2] 2} · 2H2O · 2CH3OH (2) · 10H2O (4) is synthesized by the reaction of K [FeⅢ (bpb) (CN) 2] [bpb = (CuPb (L1)] - (ClO4) 2 or [Cu2 (L2)] · (ClO4) 2 with K3 [FeⅢ (CN) The ligand was obtained by condensation of 2,6-dimethyl-p-methylphenol, ethylenediamine and triethylenediamine in a molar ratio of 1: 1: 1 while the H2L2 ligand was obtained from 2,6-dimethyl P-methylphenol and propylenediamine were condensed in a molar ratio of 1: 1. Single crystal X-ray diffraction analysis revealed that compound 1 was a complex of [FeⅢ (bpb) (CN) 2] -anion and [CuPb + Cations are arranged alternately, Compound 2 is a dumbbell-shaped five-core molecular structure composed of [Fe (CN) 6] 4-ions and two [Cu2L2] 2+ cations, Hydrogen bonds form a two-dimensional supramolecular structure.Double heteropoly complex 3 is a center-symmetric [Cu2 (L2) ] 2+ moiety and two [FeⅢ (bpb) (CN) 2] - ions containing cyano group. Octa-nuclear compound 4 is composed of three [Fe (CN) 6] [Cu2 (L2)] 2+ ions, and the magnetic investigation revealed that compounds 1, 3 and 4 all exhibited the overall antiferromagnetic behavior.
