The mixed-ligand complexes of the formula [M(CF(3)COO)(2)(MEA) (n) ] (MEA is monoethanolamine; M = Ca (I) and Sr (II), n = 1.5; M = Ba (III), (n = 1) were obtained from appropriate salts M(CF(3)COO)(2) center dot nH(2)O and MEA in ethanol. Complexes I-III were characterized by elemental analysis data and IR spectra. Slow crystallization of a solution of complex III in air gave a single crystal of the formula [Ba(CF(3)COO)(2)(MEA)(H(2)O)], which is a coordination polymer with C.N.(Ba) 9 (X-ray diffraction data). Thermal analysis showed that complexes I-III decompose under argon and in air to the corresponding fluorides at T < 400A degrees C.
