Two novel complexes, [Cd(L)(NO3)(2)(H2O)(2)] (1) and [Cd(L)(2)(NO3)(2)] (2) constructed from 3-(dimethylamino)-1-(pyridine-4-yl)prop-2-en-1-one) (L), have been synthesized and characterized by elemental analyses and single crystal X-ray diffraction. The crystal structure analysis reveals that the cadmium (II) is a seven-coordinated ion in a distorted pentagonal bipyramid environment in complex 1, while the other Cd ion is an eight-coordinated ion in a pseudo square anti-prismatic environment in complex 2. Both complexes assembled into 3D hydrogen-bonding frameworks based on C-H center dot center dot center dot O, O-H center dot center dot center dot O hydrogen bond linkages.
