Abstract

Hydrothermal reactions of lanthanide metal salts with MeN(CH(2)CO(2)H)(CH(2)PO(3)H(2)) (H(3)L) and 5-sulfoisophthalic acid monosodium salt (NaH(2)BTS) lead to four isomorphous lanthanide carboxylate-phosphonate-sulfonate hybrids, namely, Ln(H(2)L)(HBTS)(H(2)O)(2).H(2)O (Ln = La (1), Pr (2), Nd (3), Gd (4)). Their structures have been established by X-ray single-crystal diffraction. The interconnection of the lanthanide(III) ions by carboxylate-phosphonate ligands results in a 1D double chain; these double chains are further bridged by bidentate bridging carboxylate-sulfonate ligands to form a <011> layer. The luminescent properties of compounds 3 and 4 have also been studied.

摘要

镧系金属盐与MeN(CH(2)CO(2)H)(CH(2)PO(3)H(2))（H(3)L）和5-磺基间苯二甲酸单钠盐（NaH(2)BTS）的水热反应生成了四种同构的镧系羧酸盐-膦酸盐-磺酸盐杂化物，即Ln(H(2)L)(HBTS)(H(2)O)(2).H(2)O（Ln = La (1)、Pr (2)、Nd (3)、Gd (4)）。它们的结构已通过X射线单晶衍射确定。镧系(III)离子通过羧酸盐-膦酸盐配体相互连接形成一维双链；这些双链进一步由双齿桥联羧酸盐-磺酸盐配体桥联形成<011>层。还研究了化合物3和4的发光性质。
