 Title    Darstellung und Kristallstruktur einiger Tetracarboxylatoaurate(III) Preparation and Crystal Structure of Some Tetracarboxylatoaurates(III)  
 Abstract    Various salts M(AuX 4) 2 with X = OCOCH, or OCOC 2 H 5 have been prepared by two methods: (i) the reaction of metal hydroxides M(OH) 2 with HAuCl 4 , followed by treatment of the inter-mediate products with acetic or propionic acid, or (ii) the reaction of aurates M{Au(OH) 4 } 2 with the carboxylic acids. The crystal structure of Pb{Au(0C0CH 3) 4 } 2 -2H 2 0 shows that it is isostruc-tural to the strontium salt, consisting of molecular units Pb{Au(OCOCH 3) 4 } 2 with crystallo-graphic symmetry 2. The water of crystallization forms neither coordinate bonds to a metal nor hydrogen bonds. In the analogous zinc salt the water is coordinated to the zinc atom, and the structure is a layer polymer. The two compounds that crystallize in anhydrous form. Ba{Au(OCOCH 3) 4 } 2 and Pb{Au(OCOC 2 H s) 4 } 2 , have not yet yielded crystals suitable for X-ray analysis.
