Piperazinediium Diselenatohexaaquacobaltate(II) Dihydrate (C<sub>4</sub>H<sub>12</sub>N<sub>2</sub>)[Co(SeO<sub>4</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]·2H<sub>2</sub>O

Abstract

The new hybrid material, (C4H12N2)[Co(H2O)4(SeO4)2]·2H2O, has been synthesized by the slow evaporation method at room temperature and crystallographically characterized. It crystallizes in the monoclinic system, space group P21 /n. The crystal structure of this compound consists of transition metal, Co(II), octahedrally coordinated by four water molecules and two selenate groups forming the [Co(H2O)4(SeO4)2]2-anions, water molecules and piperazinediium cations (C4H12N2)2+linked together by two types of hydrogen bonds, OW–H…O and N–H…O.
