Crystalline magnesium, strontium, and barium L-glutamate complexes containing the dianion L-Glu2− have been prepared as the tetrahydrate (Mg) and hexahydrates (Sr, Ba), respectively. Their aqueous solutions have pH values of 10.45, 11.05, and 10.93, respectively. The solid state structures of the Mg and Sr complexes have been determined by single crystal X-ray methods, and the structure of the Ba analogue inferred through its isomorphism with the Sr analogue. The crystals are orthorhombic… CONTINUE READING
