A new complex of diphenylhydantoin, pentaaquabis[(5,5-diphenylhydantoinato)potassium], has been synthesized and the structure has been solved by X-ray diffraction. The crystals are monoclinic, space group C2/c, with a = 34.959(5) angstrom, b = 8.273(4) angstrom, c = 11.692(2) angstrom, beta = 109.069(13)degrees, M(r) = 670.80, V = 3196.0(17) angstrom(3), Z = 4 and R = 0.050. The potassium cations are assembled in dimers bridged through the carbonyl O atoms of the anions. The metal atom is in a distorted octahedral coordination environment.
