In the title compound, [Hg(CN)2(C6H13N)2], the HgII ion adopts an extremely distorted HgC2N2 tetrahedral coordination. The crystal packing is influenced by weak N-H...N hydrogen bonds between the amino groups and the cyanide N atoms, resulting in chains of molecules propagating in [110]. Both cyclohexylamine molecules adopt chair conformations.
