Summary From a determination of the crystal structure of KI02F2 it has been found that the I02F2-group is composed of an iodine atom forming bonds at approximately 100'with two oxygen atoms, and perpendicular to the plane of these three atoms, two opposed bonds at 180'to fluorine. The configuration may perhaps best be thought of as that of a trigonal bipyramid in which one of the three equivalent orbitals is occupied by an unshared ...
