| Abstract: | Reaction of W (CO)6 with HSC3H3N2, Et3N and Et4NCl. H2O inCH3CN afforded a mononuclear compound (Et4N] W(CO)4 (SC4H3N2)]. The crystalstructure was determined by X-ray diffraction. The crystallographic data: C16H23-N3O4SW, Mr = 537- 29, monoclinic, C2/c, a = 19. 3l7 (l0), b = 13. 75l (8), c=16. 350(8) A, β= l09. 93°, V= 4082. 7 A3, Z= 8, D.= 1. 75 g/cm', F(000) =2096, μ= 59. 0 cm-1, Final R=0. O29 and Rw= O. 036 for 2769 reflections with I>3σ(I). The X-ray structure analysis revealed that the center W atom is coordinated by Sand N atoms from 2-mercapto pyrimidine ligand and four C atoms from carbonyl,which displays a distorted octahedral geometry. |
