Crystal structure of (±)-[trans-cyclo-hexane-1,2-diylbis(aza-nedi-yl)]di-phospho-nium dibromide dichloro-methane disolvate.

The cation of the title solvated salt, C42H42N2P2 (2+)·2Br(-)·2CH2Cl2, lies on a crystallographic twofold rotation axis. The 1,2-di-amino-cyclo-hexane fragment has a chair conformation with two N atoms in a transoid conformation [N-C-C-N = 163.4 (2)°]. In the crystal, the cations are linked to the anions by N-H⋯Br and C-H⋯Br hydrogen bonds, forming a chain structure along the c axis. The di-chloro-methane mol-ecule takes part in the hydrogen-bond network through C-H⋯π and C-H⋯Br inter-actions.
