(Received 18 May 1962) The crystal structure of monoaquobisacetylacetonatozinc [Zn(CsH702)2H~O] has been determined by three-dimensional methods. The cell dimensions are a = 10.48, b = 5.37, c = 10-94 A, fl = 93°48", space group P21, with Z = 2. The structure is made up of discrete molecules, containing 5-coordinate zinc with a coordination configuration intermediate between tetragonal pyramidal and trigonal bipyramidal. Introduction Lippert & Truter (1960) have recently published a determination of the crystal structure of mono- aquobisacetylacetonatozinc, Zn(CsH~02)2.H20. Since we had an independent structure determination in the final refinement stages at the time we learned of their work, and since there appeared to be some significant differences in the results, we have com- pleted our determination.
