Offiong 1 Material Chemistry Unit, Department of Pure And Applied Chemistry, University of Calabar P.M.B. 1115- Calabar (NIGERIA) <p style="text-align: justify;">A one-dimensional Lanthanum sulphate [C<sub>4</sub>H<sub>16</sub>N<sub>3</sub>]<sub>2</sub> [La<sub>2</sub>(SO<sub>4</sub>)<sub>6</sub>], I, has be prepared by interacting diethylenetriamine sulphate with La<sup>3+</sup> ions at 100<sup>o</sup>C. The compound has been characterized with the help of powder x-ray analysis, scanning election microscopy, and infrared spectroscopy. The thermal behaviour of compound I has been studied by thermogravimetric analysis. Compound I crystallizes in monoclinic symmetry, space group P<sub>21/c</sub> (No. 14) with cell parameters a = 8.3305, b = 17.5000, c = 9.8407&Aring;, &szlig; = 101.610, vol = 143461&Aring;. The inorganic framework [La<sub>2</sub>(SO<sub>4</sub>)<sub>6</sub>]<sub>6</sub> - is anionic and charge compensation is achieved by incorporation of two molecules of fully-protonated diethylenetriamine.</p> <p>&nbsp;</p> <p>&nbsp;</p> https://journalofchemistry.org/paper/672/ Lanthanum sulphate diethylenetriamine sulphate linear chain one-dimensional structure
