Structure of strontium citrate pentahydrate

The crystal structure of tristrontium bis(2-hydroxy-1,2,3-propanetricarboxylate) pentahydrate has been determined. One Sr ion is coordinated with eight O atoms, another with nine and the third with ten at distances ranging from 2.498 (2) to 2.781 (2) A. Two Sr ions are bound to citrate ions in a tri...

Summary:The crystal structure of tristrontium bis(2-hydroxy-1,2,3-propanetricarboxylate) pentahydrate has been determined. One Sr ion is coordinated with eight O atoms, another with nine and the third with ten at distances ranging from 2.498 (2) to 2.781 (2) A. Two Sr ions are bound to citrate ions in a tridentate manner. Both citrate ions in the asymmetric unit are in an extended conformation. There are 11 hydrogen bonds in one asymmetric unit of the crystal structure.
