Pale yellow single crystals of [O=C(NPPh 3 )C(I)=C(NPPh 3 )‐C(NPPh 3 ) 2 ] + I ‐ ·1.5 thf ( 1 ·1.5 thf) have been obtained by the reaction of INPPh 3 with thallium in thf suspension. They are characterized by IR spectroscopy and by a crystal structure determination. 1 ·1.5 thf crystallizes in the monoclinic space group P2 1 /n, Z = 4, lattice dimensions at ‐83?C: a = 1101.7(1), b = 3449.0(2), c = 2000.4(1) pm, β = 104.88(1)?, R 1 = 0.0382. 1 can be understood as a cationic variation of ( Z )‐2‐butenale in which all H atoms are substituted by triphenylphosphoraneimine residues and by a iodine atom, respectively.
