title: The dimer, trimer and 1,2,4-trithiolane of adamantanethione.
abstract: The molecules of dispiro[1,3-dithietane-2,2':4,2"-diadamantane], C(20)H(28)S(2), have crystallographic C(i) symmetry, as well as local D(2h) symmetry, and a planar 1,3-dithietane ring. The molecules of trispiro[1,3,5-trithiane-2,2':4,2":6,2"'-triadamantane], C(30)H(42)S(3), have approximate C(2) symmetry and the 1,3,5-trithiane ring has a twist-boat conformation. The C-S-C bond angles within the ring are about 8 degrees larger than observed in most related 1,3,5-trithiane structures. In dispiro[1,2,4-trithiolane-3,2':5,2"-diadamantane], C(20)H(28)S(3), the molecules have local C(2) symmetry and the 1,2,4-trithiolane ring has a half-chair conformation.
