Abstract: | Abstract 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) ?, b = 8.273(4) ?, c = 11.692(2) ?, β = 109.069(13)°, M
r = 670.80, V = 3196.0(17) ?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.
Index Abstract In pentaaquabis(5,5-diphenylhydantoinato)potassium] the potassium cations are coupled in dimers through the carbonyl O atoms
of the anions.
