The title compounds, trans-bis(trans-cyclohexane-1,2-diamine)bis(6-methyl-2,2,4-trioxo-3,4-dihydro-1,2,3-oxathiazin-3-ido)copper(II), [Cu(C4H4NO4S)(2)(C6H14N2)(2)], (I), and trans-diaquabis(cyclohexane-1,2-diamine)zinc(II) 6-methyl-2,2,4-trioxo-3,4-dihydro-1,2,3-oxathiazin-3-ide dihydrate, [Zn(C6H14N2)(2)(H2O)(2)](C4H4NO4S)(2)center dot 2H(2)O, (II), are two-dimensional hydrogen-bonded supramolecular complexes. In (I), the CuII ion resides on a centre of symmetry in a neutral complex, in a tetragonally distorted octahedral coordination environment comprising four amine N atoms from cyclohexane-1,2-diamine ligands and two N atoms of two acesulfamate ligands. Intermolecular N-H...O and C-H...O hydrogen bonds produce R (2) 2(12) motif rings which lead to two-dimensional polymeric networks. In contrast, the ZnII ion in (II) resides on a centre of symmetry in a complex dication with a less distorted octahedral coordination environment comprising four amine N atoms from cyclohexane-1,2-diamine ligands and two O atoms from aqua ligands. In (II), an extensive two-dimensional network of N-H...O, O-H...O and C-H...O hydrogen bonds includes R (2) 1(6) and R (4) 4(16) motif rings.
