Insoluble coordination polymers (formula: [ Ln2 (BDC)3(H2O) 2 ]n ) with 2-D structures were obtained from the reaction of 1,3-benzenedicarboxylic acid (BDC) with Ln2O3 (where Ln=Gd, Ho) under hydrothermal conditions in the presence of 3,5-lutidine. The two compounds were characterized by single crystal X-ray diffraction. Crystal data for [Gd2 (BDC)3 (H2O)2]n:C24H16O14Gd2 ,M= 842. 9, monoclinic, space group: P21/n, a = 1. 341 nm, b= 1. 446 nm, c =data for [Ho2(BDC)3 (H2O)2]n: C24 H16O14 Ho2, M=860. 2, monoclinic, space group: P21/c,a=1.059 nm,b=14.20 nm, c=17.10 nm,β=97. 90°,V=2.548 nm3, Z=4, Mo-Kα, μ=5. 264Ln ions dimmers are interlinked together by BDC ligands with three different carboxylate groups,form intricate 2-D interconnecting tunnels with two aqua ligands inside.
