Abstract
The X-ray crystal structure of [Ru(PDTA-H)(H2O)]·H2O (1) was determined using single crystal X-ray diffraction techniques. The coordination of ruthenium in the complex is distorted octahedral with pentadentate PDTA-H and one of the four carboxylate arms uncomplexed. Ring E occurs as an envelope, while ring R1 is planar. Rings R2 and G also occur as envelopes. The structure is held in space by an elaborate network of hydrogen bonds. The kinetics of substitution reactions of H2O in complex 1 with thiourea and SCN- were studied as a function of pH (2-9), concentration of 1 and temperature. An attempt has been made to explain the lability of the complex towards substitution.
