Abstract
The structures of two Ba(II) chelates of β-diketonates have been determined; one is mononuclear and the other is multinuclear. The Ba(II) chelate of the anion of 2,2,6,6-tetramethyl-3,5-heptanedione (thd) recrystallized from pentane formed monoclinic crystals, space group I2/a, with dimensions a=24.365(9) A, b=21.174(10) A, c=48.486(16) A, β=100.98(3) o , and Z=8. This structure was determined to be a β-diketonate deficient pentanuclear complex with the formula Ba 5 (thd) 9 (HrO) 3 (OH). Both β-diketonate and water ligands act as bridges between barium ions in this structure, resulting in a thermally unstable compound
