Abstract/Summary

The title compound, poly[[mu-cyanoureato-tri-mu-hydroxidodicopper(II)] dihydrate], {[Cu-2(C2H2N3O)(OH)(3)]center dot 2H(2)O}(n), is a new layered copper(II) hydroxide salt (LHS) with cyanoureate ions and water molecules in the interlayer space. The three distinct copper(II) ions have distorted octahedral geometry: one Cu (symmetry (1) over bar) is coordinated to six hydroxide groups (4OH + 2OH), whilst the other two Cu atoms (symmetries (1) over bar and 1) are coordinated to four hydroxides and two N atoms from nitrile groups of the cyanoureate ions (4OH + 2N). The structure is held together by hydrogen-bonding interactions between the terminal-NH2 groups and the central cyanamide N atoms of organic anions associated with neighbouring layers.
