Bis[(dimethylphosphoryl)methanaminium] tetrachloridopalladate(II)

Abstract

In the crystal structure of the title compound, (C3H11NOP)2[PdCl4], (dimethylphosphoryl)methanaminium (dpmaH+) cations are connected head-to-tail by strong N—H...O hydrogen bonds, forming inversion-related cyclic dimers. The square-planar [PdCl4]2−counter-dianion is located about a center of inversion. The dications and the [PdCl4]2−dianions are connected by medium–strong N—H...Cl hydrogen bonds, forming zigzag chains parallel to [001]. Somewhat weaker N—H...Cl hydrogen bonds connect the chains into a three-dimensional network.
