Structures of some organoxenon compounds

Other examples of compounds containing Xe-C bonds are shown in Fig. 17.5.6 and described below. 

This is the first reported homoleptic organoxenon(II) compound with two Xe-C bonds of length 239 and 235 pm, longer than the corresponding bond in other compounds by about 30 pm. The C-Xe-C unit is almost linear (angle 178°) and the two C6F5 rings are twisted by 72.5° with respect to each other.

In the structure of the cation (2,6-F2H3C5N-Xe-C6F5)+, the Xe atom is (exactly) linearly bonded to C and N atoms the bond lengths areXe-C 208.7 pm and Xe-N 269.5 pm.
