Synthesis and structural characterization of {[Mn(phen)2(OAc)(H2O)]ClO4}2•H2O

The crystal structure of the title compound {[Mn(phen)2(OAc)(H2O)]CIO4)(2)(H2O)-H-. (phen = 1,10-phenanthroline) has been synthesized and determined by X-ray diffraction. The crystal is of triclinic, space group P (1) over bar with a = 12.7955(4), b = 15.0544(4), c = 16.2183(4) Angstrom, alpha = 64.479(l), beta = 67.526(l), gamma = 83.582(1)degrees, C52H40Cl2Mn2N8O15, M-r = 1197.70, V= 2600.1(1) Angstrom(3), D-c = 1.530 g/cm(3), F(000) = 1224, mu = 0.666 cm(-1) and Z = 2. The final refinement gave R = 0.0691 and wR = 0.1821 for 6131 observed reflections with I > 2sigma(I). The cell of the complex contains two uniform mono-manganese molecules [Mn(phen)(2)(OAc)(H2O)]ClO4 and a solvate water molecule. Four nitrogen atoms from two chelating phenanthroline ligands and one oxygen atom from acetate ligate to the Mn (II) ion, forming a distorted octahedral geometry together with one coordinated water molecule. One ClO4- anion and one water molecule exist outside the cation [Mn(phen)(2)(OAc)(H2O)](+) as a counter ion and solvate molecule, respectively.
