title: The geometry of the thiopeptide unit.
abstract: The structure of the modified dipeptide Z-Glyt-Gly-OBzl is reported with special emphasis on the linear and angular dimensions of the thiopeptide unit. It is shown that, except for the differences between the carbonyl and the thioacyl bond lengths, there are no significant differences between the oxopeptide and the thiopeptide unit.
