Triple hydrogen bond directed crystal engineering of metal assembled complexes: The effect of a novel organic-inorganic module on supramolecular structure
The new manganese(II) and zinc(II) triply hydrogen-bonded complexes [Hmel](2)[M(tdpd)(2)(OH2)(2)].2H(2)O (M = Mn2+ (1), Zn2+ (2); Hmel(+) = melaminium cation; H(2)tdpd = 1,4 5,6-tetrahydro-5,6-dioxo-2,3-pyrazinedicarbonitrile) have been synthesized and characterized. These complexes are isostructural as revealed by their single crystal structure analyses. Both the compounds are composed of triply hydrogen-bonded module of the AAA = DDD system.
