Novel Ladder-Like Structure Motif Assembled from Edge-Sharing Rhombus and Square of Mo2Dy2 Based on [Mo(CN)8]~(4-) and Dy~(3+) Ions as Building Blocks

摘要

A novel bimetallic 4d-4f complex, {Cs[Dy(MeOH)3(DMF)(H2O)Mo(CN)8] · 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 Dy~(3+) building blocks. Complex I crystallizes in triclinic crystal system, P1 space group, with a = 9.876(2), b = 10.300(2), c = 13.498(3) A, α = 81.96(3)°, β = 86.68(3)°, γ = 65.42(3)°, V= 1236.4(4) A~3, and Z= 2.
