[M(dap)3]InSb3S7 (M = Co, Ni): Two Novel Open-Framework Thioindate−Thioantimonates with 8-, 12-, and 16-Ring Intersecting Channels

Two novel open-framework thioindate−thioantimonates [M(dap)3]InSb3S7 [M = Co(1), Ni (2); dap = 1,2-diaminopropane] have been solvothermally synthesized and structurally characterized. 1 and 2 consist of InS4 tetrahedra and SbS33- trigonal pyramids, which are interconnected to form the first examples of three-dimensional In−Sb−S open frameworks with 8-, 12-, and 16-ring intersecting channels.
