An unusual synthetic route to the first example of a six‐membered M‐N‐P‐N‐P‐C metallacycle (M=metal atom) is reported which involves a water‐induced rearrangement of the methylated Pt‐N‐P‐C‐P‐N carbene 1 to the unique Pt‐N‐P‐N‐P‐C platinacyclocarbaphosphazene 2 . In the presence of a Lewis acid (LA), 2 converts into its orthometalated isomer 3 quantitatively. (OTf=CF 3 SO 3 ).
