| Abstract: | Compounds with a general formula Cat]In(H2O) n (SO4)2] x · mH2O (where Cat = C(NH2)3, H(2,2′-Bipy), H2(4,4′-Bipy), H2Py(CH2)3Py], and H3N(CH2)6NH3) were synthesized and identified from the elemental analysis, IR, and thermogravimetric analysis data. X-ray diffraction analysis of crystalline C(NH2)3]In(H2O)2(SO4)2] complex showed that the polymer chains of In aquasulfate form ensembles with guanidinium ions. The structure of H2(4,4′-Bipy)]In2(H2O)6(SO4)4] · 2H2O consists of the dimeric anions of indium sulfate. The coordination sphere of In includes three O atoms of three SO4 groups and three O atoms of water molecules. The dimers are united into framework by diprotonated Bipy cations. |
