Crystal-Structures of the Isomorphous Prototypic Oxo-Centered Trinuclear Complexes (Cr3O(Oocch3)(6)(H2O)(3))Cl-Center-Dot-6H(2)O and (Fe3O(Oocch3)(6)(H2O)(3))Cl-Center-Dot-6H(2)O
The two compounds [Cr3O(OOCCH3)(6)(H2O)(3)]Cl . 6H(2)O and [Fe3O(OOCCH3)(6)(H2O)(3)]Cl . 6H(2)O are the prototypes of the general class of trinuclear "basis carboxylates". New single-crystal X-ray structure determinations show that the two compounds are strictly isomorphous, with little disorder, and make it possible to quantify the extents of distortion of the molecules from idealized trigonal geometry.
