摘要：

Three lanthanide coordination polymers were prepared by hydrothermal synthesis and characterized by single-crystal X-ray diffraction. [Pr-2(mBDC)(3)(phen)(H2O)](n).0.5n H2O (1) (mBDC = isophthalate, phen = 1,10-phenanthroline) exhibits two kinds of metal environments (coordination numbers 7 and 8). In complex 1, mBDC ligands adopt the tetradentate (bridging and bridging) coordination mode and connect Pr ions into an undulating layer, and a 3D supramolecular structure is formed via hydrogen bonds between adjacent layers. [Tb-4(mBDC)(6)(phen)](n) (2) has three types of metal environments (coordination numbers 6, 7 and 8) and is composed of a 3D network formed by mBDC linking Tb ions via tetradentate (bridging and bridging) and pentadentate (bridging/chelating and bridging) coordination modes. There are two kinds of small quadrilateral channels along the a-axis. [Er-4(mBDC)(6)(phen)](3) (3) is isostructural to complex 2. (C) 2003 Elsevier B.V. All rights reserved.
