Abstract :
The cation of the title solvated salt, C42H42N2P22+·2Br−·2CH2Cl2, lies on a crystallographic twofold rotation axis. The 1,2-diaminocyclohexane 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 dichloromethane molecule takes part in the hydrogen-bond network through C—H⋯π and C—H⋯Br interactions.
