Crystal structure of potassium tris(acetylacetonato)cadmate(II) monohydrate

Abstract

The crystal structure of the title compound has been determined from single-crystal X-ray diffractometer data by the heavy-atom method, and refined to R 0·071 (1997 observed reflections) by block-diagonal least-squares. Crystals are monoclinic, P2₁/a, a= 16·46(1), b= 14·051(6), c= 8·404(3)Å, β= 101·60(3)°, Z= 4. The structure is comprised of discrete potassium cations and [Cd(C₅H₇O₂)₃]^– anions, in which the metal atom is co-ordinated by the three ligands. with Cd–O 2·247(7)–2·325(9)Å, in a very good approximation to trigonal prismatic stereochemistry. The potassium environment is comprised of five of the six ligand oxygen atoms and the water molecule, with K–O 2·622(11)–2·802(8)Å.
