Structure of 2,4-dinitrobenzenesulphenylimino(triphenyl)phosphorane, Ph3PNSC6H3(NO2)2-2,4

Abstract

The compound Ph3PNSC6H3(NO2)2-2,4 was isolated from the reaction of the 2,4–dinitrobenzenesulphenamide of 1,4-dihydro- 1,4- iminonaphthalene with trans-[IrCl(CO)(PPh3)2], and its structure has been determined. Bond angles at N [123.1(5)°] and S [101.4(5)°] and the bond distances P[double bond, length half m-dash]N [1.566(7)Å], S–N [1.660(8)Å], and C–S [1.728(11)Å] indicate the presence of localised double and single bonds with no significant declocalisation of the lone-pair charge at nitrogen. The 2,4-dinitrophenyl ring is –8.9° out of the N,S,C plane and the PNSC torsion angle is –134.6°.
