The title compounds C13H26N+Cl- (N,N-dicyclohexylmethylammonium chloride), C13H26N+Br- (N,N-dicyclohexylmethylammonium bromide) and C13H26N+I- (N,N-dicyclohexylmethylammonium iodide) areisostructural and crystallize in the orthorhombic space group Pna2(1) with the lattice parameters a=7.580(1), b=19.072(1), c=9.165(1) angstrom, V=1321.5(1) angstrom(3) for X=Cl, a= 7.765(1), b = 19.054(1), c=9.270(1) angstrom, V=1371.5(1) angstrom(3) for X= Br, and a= 8.102(1), b=19.084(1), c=9.535(1)angstrom , V= 1474.2(1) angstrom(3) for X= I with Z=4 for each compound. Their cyclohexyl groups are aligned along [010] while their halide ions are coordinated along [100] by a strong linear N-H center dot center dot center dot X (X= Cl, Br, I) hydrogen bond. Fourier-transform infrared spectra show a decreasing hydrogen bond acceptor strength from the chloride to the iodide.
