SYNTHESES, STRUCTURES, AND THERMAL-PROPERTIES OF HETEROMETALLIC COPPER(II)-ALKALINE-EARTH METAL-COMPLEXES WITH 1,3-BIS(DIMETHYLAMINO)-2-PROPANOLATO (BDMAP) AND TRIFLUOROACETATO AS LIGANDS - CACU(BDMAP)(2)(O2CCF3)(2)(H2O), SR2CU2(BDMAP)(4)(O2CCF3)(4), AND SR2CU(BDMAP)(6)(O2CCF3)(4)(MU(3)-OH)(2)

Three new heterometallic copper(II)-alkaline-earth metal complexes hav e been synthesized by using 1,3-bis-(dimethylamino)-2-propanolato (bdm ap) and trifluoroacetato as ligands. These three compounds have been f ormulated as CaCu(bdmap)(2)(O2CCF3)(2)(H2O) (1), Sr2Cu2(bdmap)(4)(O2CC F3)(4) (2), and Sr2Cu4(bdmap)(6)(O2CCF3)(4)(mu(3)-OH)(2) (3), respecti vely. Their structures have been determined by single-crystal X-ray di ffraction analyses. Compound 1 is a dinuclear complex and dimerizes in the solid state through intermolecular hydrogen bonds. Compound 2 is a tetranuclear complex, while compound 3 is a hexanuclear complex, whe re metal ions are linked together through the bridging ligands. The th ermal properties of these compounds have been investigated by thermogr avimetric analysis. These compounds decompose to either the correspond ing oxide or a mixture of metal fluoride and oxides at temperatures be low 400 degrees C.
