Three new indium oxalates, formulated as H(3)dpta center dot In(C2O4)(H2O)(3)center dot 2SO(4) (1), In(qd)(C2O4)(1.5)center dot 1.5H(2)O (2), and H(2)bpp center dot In-2(C2O4)(4) (3) in which dpta = dipropylenetriamine, qd = quinoxaline-2,3(1H,4H)-dione, and bpp = 1,3-bis(4-piperidyl)propane, were prepared in the presence of different amines. These compounds have cationic, neutral, and anionic frameworks, respectively. Topological analyses reveal that compound 2 has an hcb net, while compound 3 has a dia net. The photoluminescent property of compound 2 was also investigated. (C) 2017 Published by Elsevier B.V.
