Crystal structure of N,N'-bis-(pyridin-4-ylmeth-yl)cyclo-hexane-1,4-di-ammonium dichloride dihydrate.

ABSTRACT: Treatment of N,N-bis-(pyridin-4-ylmeth-yl)cyclo-hexane-1,4-di-amine with hydro-chloric acid in ethanol led to the formation of the title salt, C₁₈H₂₆N₄²⁺·2Cl^-·2H₂O, which lies about a crystallographic inversion center at the center of the cyclo-hexyl ring. The asymmetric unit therefore comprises one half of the N,N-bis-(pyridin-4-ylmeth-yl)cyclo-hexane-1,4-di-ammonium dication, a chloride anion, and a solvent water mol-ecule. In the dication, the two trans-(4-pyridine)-CH₂-NH₂- moieties occupy equatorial sites at the 1- and 4-positions of the central cyclo-hexyl ring, which is in a chair conformation. The terminal pyridine ring is tilted by 27.98 (5)° with respect to t
