摘要：
Novel zinc thiodiacetate complex [Zn(tda)(H2O)](n) (1) (tda = S(CH2COO)(2)(2-)) was obtained from the reaction of aqueous solutions of 2 zinc dichloride with a 1: 1 mixture of Na2CO3 and thiodiacetic acid. Complex 1 is a different hydrate compound with respect to the known species [Zn(tda)(H2O)(3)] center dot H2O. The selective formation of 1 or [Zn(tda)(H2O)(3)] center dot H2O can be achieved by controlling the crystallization conditions and it is even possible to interconvert the two hydrate compounds by fast or slow crystallization processes. The reaction of 1 with o-phenanthroline (phen) gave the dinuclear compound [Zn(tda)(phen)](2) center dot 5H(2)O (2), which was identified by X-ray analysis. The water crystallization molecules are interconnected by hydrogen bonds and they are aligned inside channels, which are parallel to the c-axis. (c) 2005 Elsevier B.V. All rights reserved.
