Cis-Aqua-bis-(2,2'-bipyrimidine-?N,N)iodidomanganese(II) iodide dihydrate.

ABSTRACT: The asymmetric unit of the title compound, [MnI(C(8)H(6)N(4))(2)(H(2)O)]I·2H(2)O, contains a cationic Mn(II) complex, an I(-) anion and two solvent water mol-ecules. In the complex, the Mn(II) ion is six-coordinated in a considerably distorted octa-hedral environment defined by four N atoms of the two chelating 2,2'-bipyrimidine (bpym) ligands, one I(-) anion and one O atom of a water ligand. As a result of the different trans effects of the I and O atoms, the Mn-N bond trans to the I atom is slightly longer than the Mn-N bond trans to the O atom. The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.088?(4)?Å] is 76.48?(6)°. In the crystal, the complex cation, the anion and the solvent water mol-ecules are linked by inter-molecular O-H?O, O-H?I and O-H?N hydrogen bonds.
