Abstract
Crystals of 2-amino-6-methylpyridinium dihydrogenmonophosphate (denoted as 2A6MPP) and 2-amino-6-methylpyridinium dihydrogenmonoarsenate (denoted as 2A6MPAs), have been prepared and grown at room temperature. They crystallize with triclinic unit cells and are isotopic. The following unit cell parameters were found, (2-NH2-6-CH3C5H4N)H2PO4: a = 7.5165(6), b = 8.2640(5), c = 8.5674(7) Ã
, α = 64.845(5), β = 80.156(3), γ = 85.783(5), Z = 2, V = 474.61(6) Ã
3; (2-NH2-6-CH3C5H4N)H2AsO4: a = 7.6011(4), b = 8.4261(6), c = 8.7074(6) Ã
, α = 64.228(3), β = 81.047(4), γ = 85.972(4), Z = 2, V = 496.09(6) Ã
3. The common space group is P1¯. We have determined the structure of the phosphate. It exhibits infinite (H2PO4)nân chains. The organic groups (2-NH2-6-CH3C5H4N)+ are anchored between adjacent polyanions through multiple hydrogen bonds. The thermal property of the compound was investigated as well as was the IR property supported by group theoretical analyses.
