Metal (Li, GeII, GeIII, SnII, and PbII) 2,6-dialkylbenzenethiolates; X-ray crystal structures of Sn(SAr)2(Ar = C6H2But3-2,4,6) and [M(SAr′)2]3(M = Sn or Pb, Ar′= C6H3Pri2-2,6)

Abstract
Complexes [Li(SAr)(OEt2)]n, M(SAr)2[Ar = C6H2But 3-2,4,6; M = Ge, Sn (3b), or Pb], [Cr(CO)5{Sn(SAr)2}], Sn(I)(Me)(SAr)2, ·Ge(SAr)3(7a), and [M(SAr′)2]3[Ar′= C6H3Pri 2-2,6; M = Sn (8a) or Pb (8b)] are hydrocarbon-soluble and crystalline [except for the transient (7a]; X-ray structures of the title complexes (3b)[a V-shaped monomer with an SSnS angle of 85.4(1)° and Sn–Sav 2.435(1)Å] and (8)[M(SAr′)(µ-SAr′)2M(µ(SAr′)2M(SAr′)] reveal metal co-ordination numbers of 2 for the former or 3, M(terminal) and 4, M(central) for the latter, Sn–St 2.471(5), mean Sn–Sbr 2.66(10), Pb–St 2.554(4), and mean Pb–Sbr 2.76(9)Å.
