Two new indium coordination polymers formulated as [In(BPDA)(phen)Cl] n (1) and [In(BDC)(HBDC)·2DMF]n (2) (H 2BPDA = 2,2′-biphenyldicarboxylic acid, C14H 10O4; phen = 1,10-phenanthroline, C12H 8N2; H2BDC = 1,3-benzenedicarboxylic acid, C8H6O4; DMF = N,N-dimethylformamide, C 3H7NO) have been synthesized under solvothermal conditions and characterized by single-crystal X-ray diffraction, infrared (IR), thermal gravimetric analyses (TG) and luminescent studies. Molecular structural analyses reveal that complex 1 exhibits an indium-2,2′-biphenyldicarboxylate helical chained structure decorated with 1,10-phenanthroline, and complex 2 possesses a two-dimensional (2D) layered structure constructed by 1,3-benzenedicarboxylate ligands and InO6 octahedra, which has a (4,4) topological structure. Blue-green emission at 480 nm (λ ex = 340 nm) for 1, intense blue-green emission at 492 nm, green emission at 535 nm, and yellow-green emission at 576 nm (λex = 340 nm) for 2 are observed in the solid state at room temperature. © 2013 Published by Elsevier B.V.

Using H3PO3 as a phosphorus source and oxalic acid as a reducing agent, the first three-dimensional open-framework gallium phosphate-phosphite formula as (C6N2H18)2(C6N2H17)Ga15(OH)8(PO4)2(HPO4)12(HPO3)6·2H2O (1), has been hydrothermally synthesized in the presence of N,N,N′,N′-tetramethylenediamine (TMEDA) as a structure-directing agent. Compound 1 crystallizes in trigonal system with space group P - 3, a = b = 19.046(3) Å, c = 8.3306(17) Å, γ = 120°, V = 2617.1(7) Å3, and Z = 1. Its 3-D network is based on alternated Ga-centered (GaO4 tetrahedra, GaO5 trigonal bipyramids, and GaO6 octahedra) and P-centered (PO4 3-, HPO4 2-, and HPO3 2-) units. Protonated organic amines and water molecules are located in the 12-membered ring channels. © 2010 Elsevier Ltd. All rights reserved.

Three new gallium phosphite-oxalates formula as (C6N2H14)2[Ga2(OH)2(C2O4)2(HPO3)2]·2H2O (1), (C6N2H18)0.5[Ga(OH)(C2O4)0.5(HPO3)] (2), and Ga(C2O4)0.5(C3N2H4)(HPO3) (3) have been hydrothermally synthesized by controlling the pH value of the reaction system. Compound 1 possesses a one-dimensional ladder-like chain structure, in which the C2O4 2- anion is coordinated to one Ga center and acts as mono-bidentate ligand. In 2 and 3, the C2O4 2- anions serve as bis-bidentates ligands bridging between two Ga atoms to form the two-dimensional layered structures. Furthermore, compound 3 displays a neutral layered network, which is decorated by the directly coordinated organic ligand. © 2010 Elsevier Masson SAS. All rights reserved.
