摘要：

Two new organic monophosphates, C3H12N22+ . HPO42- . H2O (DAPHP) and C6H18N32+ . 2HPO(4)(-) . 4H(2)O (TMEDH2P), are obtained by action of H3PO4 with respectively 1,2-diaminopropane and N,N,N',N'-tetramethylethylenediamine. DAPHP is monoclinic, P2(1)/n, with a = 10.653(3) Angstrom, b = 6.025(1) Angstrom, c = 13.159(2) Angstrom, beta = 92,37(2)degrees, Z = 4, and rho(measd) = 1.48 g/cm(3). Its atomic arrangement is described by infinite polyanions, (HPO4)(n)(2n-), organized in ribbons alternating with organic cations, TMEDH2P is triclinic, with a = 8.209(2) Angstrom, b = 8.423(2) Angstrom, c = 8.709(2) Angstrom, alpha = 96,70(2)degrees, beta = 113,88(2)degrees, gamma = 118.02(1)degrees, Z = 1, and rho(measd) = 1.39 g/cm(3). Its structure exhibits infinite (H2PO4)(n)(n-) chains where organic cations are anchored between adjacent polyanions, In both structures a network of strong hydrogen bonds connects the different components in the building of the crystal.
