Abstract
Cu(CF3COO)(2) (I) and Cu(CHF2COO)(2). 5H(2)O (II) were synthesized and stud ied by X-ray diffraction analysis. Crystals I are orthorhombic, a = 16.970( 6), b = 10.515(4), c = 9,041(3) Angstrom, V = 1613(1) Angstrom(3) space gro up Pcca, Z = 8, R-1 = 0.0350. Crystals II are monoclinic, a = 12.770(2), b = 13.493(2), c = 8.704(1) Angstrom, beta = 90.09(2)degrees, V = 1499.7(4) A ngstrom(3), space group C2/c, Z = 8, R-1 = 0.0374. The coordination environ ment of the Cu atom in I is trigonal-bipyramidal with Cu-O distances of 1.9 09-2.441 Angstrom in the dimeric structural units and 2.058 Angstrom betwee n the dimers. In structure II, the copper coordination geometry is tetragon al-pyramidal with Cu-O distances of 1.935-2.315 Angstrom.
