A new binuclear complex {[Cd(phen)(2)(H2O)] . (TMA)(2-)}(2) has been synthesized and it can undergo single-crystal-to-single-crystal (SCSC) transformation to a new mononuclear complex [Cd(phen)(3)] . 2(HTMA)(-) . H(2)TMA} by a simple in-situ solvent evaporation method at room temperature without changing the reaction system.
A new binuclear complex {[Cd(phen)(2)(H2O)] . (TMA)(2-)}(2) has been synthesized through the reaction of o-phenanthroline (phen), 3-thiophenemalonic acid (H(2)TMA), and cadmium acetate in a 1 : 2 (v/v) EtOH-H2O mixture at room temperature. This complex can undergo single-crystal-to-single-crystal (SCSC) transformation to a new mononuclear complex [Cd(phen)(3)] . 2(HTMA)(-) . H(2)TMA} by a simple in-situ solvent evaporation method at room temperature without changing the reaction system. In the whole SCSC process, with the solvent water molecules decreasing and the concentration of ligands increasing, the phen ligands replace the coordination water and coordinate with cadmium ions, finally resulting in the crystal structure transformation in the solid state.
