Abstract
New supramolecular synthon induced complex [Zn(Hor)(Hiso)·3H2O]·H2O (1) is obtained in a selfassembly reaction of zinc nitrate with orotic (H3Or, 1,2,3,6-tetrahydro-2,6-dioxo-4-pyrimidinecarboxylic) acid and isonicotinamide. The isonicotinamide molecule is hydrolyzed in-situ into isonicotinic (Hiso, pyridine-4-carboxylic) acid. A detailed structural analysis and the role of hydrogen bonding synthons in deciding the overall structural diversity is discussed. The {…H–N–C=O…}2 and {…H–O–C=O…}2 dimers play an important role in the metal-organic architecture of 1. Complex 1 is insoluble in almost all organic solvents as well as in water. The complete decomposition of the compound is achieved above 445°C.
