摘要
A novel 3d-4f heterometallic coordination polymer, {[Tm<sub>5sub>(渭<sub>3sub>-OH)<sub>2sub>(BDC)<sub>6sub>(IN)<sub>2sub>Cu(H<sub>2sub>O)<sub>2sub>]路(H<sub>2sub>O)<sub>3sub>}<sub>nsub> (1) [BDC聽=聽benzene-1,2-dicarboxylate, IN聽=聽isonicotinate], has been hydrothermally synthesized and structurally characterized by single crystal X-ray diffraction, FTIR, elemental analysis, powder X-ray diffraction and thermogravimetric analysis. The compound crystallizes in monoclinic system, space group P2<sub>1sub>/c (No. 14), a聽=聽13.7302(5) 脜, b聽=聽23.5428(3) 脜, c聽=聽21.5789(2) 脜, 尾聽=聽91.491(3)掳, V聽=聽6973.0(3) 脜<sup>3sup>, and Z聽=聽4. The structure exhibits unusual two-dimensional Tm-carboxylate layer, which is constructed from the expansion of novel pentanuclear {Tm<sub>5sub>} clusters. More interestingly, the heterometallic Cu(I) ions were successfully planted into such Ln-carboxylate layer by the bifunctional IN bridging ligands, resulting in the formation of an unprecedented 2D heterometallic lanthanide-transition-metal framework.
