Synthesis, crystal structure and magnetic properties of a three-dimensional cyano-bridged heterometallic complex {NiII(Me6-[14]ane-N4)}2[WIV(CN)8] · 6H2O

Self-assembly of [W(CN)8]4− and {Ni(Me6-[14]ane-N4)}2+ (Me6-[14]ane-N4 = 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane) leads to a novel three-dimensional cyano-bridged complex {Ni(Me6-[14]ane-N4)}2[W(CN)8] · 6H2O (1), which was characterized by IR, elemental analysis, ICP, TGA and SC-XRD. Magnetic behavior of the complex shows a characteristic of combination of zero-field splitting of Ni2+ in an axially distorted octahedral surrounding and a weak antiferromagnetic interaction between Ni2+ ions through the diamagnetic [W(CN)8]4− bridges.
