Description
Summary:The asymmetric unit of the title structure, C3H11NOP+·I−·C3H10NOP, consists of one (dimethylphosphoryl)methanamine (dpma) molecule, one (dimethylphosphoryl)methanaminium (dpmaH) ion and one iodide counter-anion. In the crystal, medium–strong to weak N—H...O and N—H...N hydrogen bonds connect dpmaH cations and dpma molecules into strands along [001]. The iodide counter-anions form only very weak hydrogen bonds. The crystal used for the diffraction study was found to be an inversion twin with a ratio of 0.83 (2):0.17 (2). The title structure is isotypic to that of dpmaH[ClO4]·dpma [Buhl et al. (2013). Crystals 3, 350–362].
