Abstract

In the crystal structure of the title compound, C(6)H(16)N(2)O(3) (2+)·SO(4) (2-), each cation forms three O-H⋯O and five N-H⋯O hydrogen bonds to six neighbouring sulfate anions. In addition, interlinking of the cations by N-H⋯O interactions is also observed. The cyclo-hexane ring adopts a chair conformation with two axial hy-droxy groups. Although the separation of 2.928 Å is almost ideal for a hydrogen bond, intra-molecular hydrogen bonding between these two hy-droxy groups is not observed.
