(a)–(d) The molecular conformations and atom-numbering schemes for compounds (1)[link]–(4)[link], respectively. Displacement ellipsoids are drawn at the 50% probability level. For compounds (2)[link]–(4)[link], only hetero atoms are labelled; the C-atom labels in (2)[link]–(4)[link] are analogous to those shown for (1)[link].
