Structural properties of trans-cyclohexane-1,2-diamine complexes of copper(II) and zinc(II) acesulfamates.

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(C(4)H(4)NO(4)S)(2)(C(6)H(14)N(2))(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(C(6)H(14)N(2))(2)(H(2)O)(2)](C(4)H(4)NO(4)S)(2)·2H(2)O, (II), are two-dimensional hydrogen-bonded supramolecular complexes. In (I), the Cu(II) 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.
