X -Ray crystal and multinuclear n.m.r. study of FXeN(SO 2 F) 2 ; the first example of a xenon–nitrogen bond

An X-ray crystallographic study has shown that FXeN(SO2F)2 contains an Xe–N bond, representing the first definitive proof for its existence; solution 15N and 129Xe n.m.r. studies of 15N-enriched FXeN(SO2F)2 also demonstrate that this bond is present in solution.
