What is Crystal Structures and Thermal Behavior of Two New Organic Monophosphates about?

Two new organic monophosphates, C3H12N 2؉ 2 • HPO 2؊ 4 • H2O (DAPHP) and C6H18N 2؉ 3 • 2HPO ؊ 4 • 4H2O (TMEDH2P), are obtained by action of H3PO4 with respectively 1,2-diaminopropane and N,N,N,N-tetramethylethylenediamine. DAPHP is monoclinic, P21/n, with a ‫؍‬ 10.653(3) A s , b ‫؍‬ 6.025(1) A s , c ‫؍‬ 13.159(2) A s , ‫؍‬ 92.37(2)°, Z ‫؍‬ 4, and measd ‫؍‬ 1.48 g/cm 3 . Its atomic arrangement is described by infinite polyanions, (HPO4) 2n؊ n , organized in ribbons alternating with organic cations. TMEDH2P is triclinic, with a ‫؍‬ 8.209(2) A s , b ‫؍‬ 8.423(2) A s , c ‫؍‬ 8.709(2) A s , ‫؍‬ 96.70(2)°, ‫؍‬ 113.88(2)°, ‫؍‬ 118.02(1)°, Z ‫؍‬ 1, and measd ‫93.1؍‬ 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.
