Syntheses and Crystal Structures of Two Octacyanometalate Networks:Ni(L1)3W(CN)82·4H2O and Ni(L2)2Mo(CN)8·8H2O

摘要

@@1.Introduction Recently, octacyanometallated-based assemblies have played an important role in the construction of molecule-based functional materials owing to their unique structures and physicochemical properties.[1] However, only several NiⅡ/MⅣ/Ⅴ (M=Mo, W, and Nb) networks have been reported so far. To extend the properties-structural correlation of this system, we have obtained two-and three-dimensional bimetallic assemblies [NiⅡ(LⅠ)]3[WⅤ(CN)8]2·4H2O (L1=3,10-dipropyl-1,3,5,8,10,12 -bexaazacyclotetradecane), 1, and [NiⅡ(L2)]2[MoⅣ(CN)8]·8H2O (L2=3,10-diethyl-1,3,5,8,10,12 -hexaazacyclotetradecane), 2. Single crystals of 1 and 2 were obtained successfully by slow diffusion and characterized structurally by single-crystal X-ray diffraction.
