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-NH{sub 2}-6-CH{sub 3}C{sub 5}H{sub 4}N)H{sub 2}PO{sub 4}: a=7.5165(6), b=8.2640(5), c=8.5674(7)A, {alpha}=64.845(5), {beta}=80.156(3), {gamma}=85.783(5), Z=2, V=474.61(6)A{sup 3}; (2-NH{sub 2}-6-CH{sub 3}C{sub 5}H{sub 4}N)H{sub 2}AsO{sub 4}: a=7.6011(4), b=8.4261(6), c=8.7074(6)A, {alpha}=64.228(3), {beta}=81.047(4), {gamma}=85.972(4), Z=2, V=496.09(6)A{sup 3}. The common space group is P1-bar . We have determined the structure of the phosphate. It exhibits infinite (H{sub 2}PO{sub 4}){sub n}{sup -n} chains. The organic groups (2-NH{sub 2}-6-CH{sub 3}C{sub 5}H{sub 4}N){sup +} 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.
