Synthesis and X-ray crystal structure of ( p-CH 3C 6H 4) 3AsNS 3N 3

Abstract

A 1:2.5 mole ratio reaction of S 4N 4 with ( p-tolyl) 3As in a solvent mixture of CH 3CN and C 6H 6 at ca. 50 °C gives ( p-CH 3C 6H 4) 3AsNS 3N 3 in ca. 75% yield after a two day reaction period. The compound, ( p-CH 3C 6H 4) 3AsN-S 3N 3 crystallizes in the triclinic space group P 1 with a=9.216(2) A ̊ , b=11.124(4) A ̊ , c=12.398(4) A ̊ , α=76.43(2)°, β=83.06(2)° γ=67.09(2)°, V=1137.4(6) A ̊ 3, Z=2 . The structure is refined to a final R value of 0.047 with R w=0.049. The AsN bond distance is 1.78 Å while the average SN ring distance is 1.62 Å.
