Abstract
Two cyano-bridged trinuclear bimetallic assemblies, [CuII(C8H18N2)2]2[MIV(CN)8]·H2O [M = Mo (1), W (2)], were synthesized by solution of Cu(ClO4)2·6H2O and (+)-cis-1,2,2-trimethyl-1,3-diamino-cyclopentane reacting with K4[Mo(CN)8]·2H2O and Cs3[W(CN)8]·2H2O, respectively. The X-ray crystallography reveals that complexes 1 and 2 are all crystallized in triclinic, P1¯ space group. The single crystal structures of 1 and 2 show each unit cell consists centrosymmetrically of two chiral molecules of Cu2M(CN)8 unit, further leading to the racemization completely. The magnetic investigation exhibits paramagnetic behavior for 1 and very weak antiferromagnetic properties for 2 because the different diamagnetic MIV(CN)8 ion bridges between CuII ions.
