Two new organic-selenate salts: Syntheses and crystal structures of bis(di-iso-propylammonium) selenate and di-n-butylammoniumhydrogenoselenate

Two new dialkyammonium selenate salts [i-Pr2NH2]2[SeO4] (1) and [n-Bu2NH2][HSeO4] (2) have been isolated and characterized by single-crystal X-ray diffraction. Salt 1 crystallizes in the monoclinic system, space group P21/n with a?=?8.7190(5), b?=?8.8500(4), c?=?22.5953(9) Å, ??=?94.6290(17)°, V?=?1737.84(14) Å3 and Z?=?4. Salt 2 crystallizes in the monoclinic system space group P21/n with a?=?10.9328(9), b?=?8.1700(6), c?=?13.8095(11) Å, ??=?97.130(3)°, V?=?1223.94(17) Å3 and Z?=?4. In both salts, dialkylammonium cations and selenate anions are connected through NH?·?·?·?O and OH?·?·?·?O hydrogen bonds. In the crystal structure, 1 and 2 are organized in layer-like arrangements. Structural characterizations were completed by infrared and 1H, 13C{1H} and 77Se NMR spectroscopy and elemental analysis which corroborate the X-ray elucidations.
