Novel ladder-like structure motif assembled from edge-sharing rhombus and square of Mo2Dy2 based on [Mo(CN)8]4− and Dy3+ ions as building blocks
摘要:
A novel bimetallic 4d-4f complex, {Cs[Dy(MeOH)(3)(DMF)(H2O)Mo(CN)(8)] center dot H2O}(n) (I) (DMF = N,N'-dimethylformamide), has been synthesized and structurally characterized. The crystal analyses showed that complex I consists of a one-dimensional infinite chain, which adopts a 1D ladder-like structure motif assembled from an edge-sharing rhombus and square of Mo2Dy2. This is the first structurally characterized example of a 1D ladder structure based on the [Mo(CN)(8)](4-) and Dy3+ building blocks. Complex I crystallizes in triclinic crystal system, P (1) over bar space group, with a = 9.876(2), b = 10.300(2), c = 13.498(3) angstrom, alpha = 81.96(3)degrees, beta = 86.68(3)degrees, gamma = 65.42(3)degrees, V = 1236.4(4) angstrom(3), and Z = 2.
