摘要
在过去的几十年里.以Mo(W)/Cu/S簇合物为前驱物进行含簇配位聚合物的自组装一直让化学工作者对此怀有浓厚的研究兴趣。这主要是因为此类化合物不仅具有丰富的化学结构。而且在光学材料、吸附材料、生物化学等方面都具有重要的用途肚121。例如,含簇三维聚合物{[WSCu4(4,4’-bipy)4][WS4Cu4I4,4'-bipy)2]}∞不仅具有漂亮的孔洞结构,
Treatment of (Bu4N)2[WOS3Cu3(NCS)3] with equimolar 4,4'-bipy in aniline afforded one polymeric cluster {[WOS3Cu3(NCS) (ani)2(4,4'-bipy)1.5]·2 (ani)}n (ani =aniline). It was characterized by elemental analysis, IR spectra, and thermal analysis. It crystallizes in a triclinic system space group P1 with a=1.217 9(2) nm, b=1.326 9(3) nm, c= 1.7202(3) nm, α=70.77(3)°,β=70.01(3)°, γ=76.47(3)°, V=2.443 5(10) nm^3, Z=2, F(000)=1 138, Dc=1.565 g·cm^-3,μ= 3.842 mm^-1, R=0.067 2, wR =0.188 91, S= 1.131. The incomplete cubane-like [WOS3Cu3] core in (Bu4N)2[WOS3Cu3 (NCS)3] was retained in the structure of this polymer. The aniline molecules served not only as a solvent but also as a ligand, affording a [WOS3Cu3(NCS)(ani)2] cluster core. Such cores are linked ahematively through single 4,4'-bipy bridges and double 4,4'-bipy bridges, thereby forming a 1D zigzag chain structure. CCDC: 683872.
