摘要
A new cyano bridged assembly,2·5H2O, prepared by slow diffusion of an aqueous solution of K2 and an aqueous solution of ClO4 in an U tube, has been characterized by X ray structure analysis, IR and magnetic measurements. The crystal crystallizes in orthorhombic, space group Pnna, a=2.8189(5)nm, b=0.8407(2)nm, c=1.4554(2)nm, V= 3.4491(11)nm3 and Z=4. The complex is built up of infinite chains which are formed by trans Ni(en)2 μ (NC)2, cis μ (NC)2Ni(CN)2 and cis μ (CN)2Ni(en)2 groups. The variable temperature magnetic susceptibility has been measured in the 5～300K range. A magnetic susceptibility study indicates the presence of a weak antiferromagnetic interaction and gives it’s weiss constant θ=2.6K. CCDC: 207329.
