Piperazinediium Diselenatohexaaquacobaltate(II) Dihydrate (C₄H₁₂N₂)[Co(SeO₄)₂(H₂O)₄]·2H₂O

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.

Benzopyrazinoisoindigo or Its Reduced Form? Synthesis, Clarification, and Application in Field‐Effect Transistors

“…Many double sulfates combining transition metal and amine, which crystallize all in a supramolecular fashion, have been prepared at room temperature and characterized 9–22. However, an examination of the literature shows that a few hybrid selenate‐containing transition metals have been reported 23–28. In order to expand upon the emergent chemistry of organically templated metal selenate, a new compound using 1,4‐diaza‐bicyclo[2.2.2]octane as a template and copper as transition metal was synthesized.…”

“…[23][24][25][26][27][28] In order to expand upon the emergent chemistry of organically templated metal selenate, a new compound using 1,4-diaza-bicyclo[2.2.2]octane as a template and copper as transition metal was synthesized. In this paper, we report chemical preparation, infrared spectroscopy analysis, structural study, and thermal behavior of this new compound.…”
