摘要
Four novel heterothiometallic cluster polymers based on a [MoOS3Cu3] unit have been synthesized by the solution self-assembly of 4,4'-bipy (4,4'-bipy bpy) with [NH4](2)MoS2O2 and CuX (X = I, Br, or SCN) in the presence of different organic cation-templates [DMI]center dot I, [C-6(Mim)(2)]center dot Br-2, [C-3(Mim)(2)]center dot Br-2, and [BBP]center dot Br-2: Compounds {[MoOS3Cu3I(mu-bpy)(2.5)]center dot 2.5DMF}(infinity) (1), {[MoOS3Cu3I(mu-bpy)(2.5)]center dot DMF}(infinity) (2), and {[MoOS3Cu3Br(mu-bpy)(2.5)]center dot 2.5DMF}(infinity) (3) are isomorphous neutral 3D 4-fold interpenetrating architectures with a (6, 4) node, while polymer [MoOS3Cu3(NCS)(mu-bpy)(2.5)](infinity) (4) is a 3D architecture with a (6(4) 8(2)) net displaying self-interpenetrating features. All of them have been characterized by single-crystal X-ray diffraction, elemental analysis, IR, TGA, and UV-vis. The results may provide fascinating insights into the template effect on the construction of the cluster-based coordination polymers.
