(a) The overlap of the two independent molecules (A and B) in (I), after a least-squares fit of their `skeletal spine', viz. C11—C21(O1)—C31—N2—C13—C23. (b) The same as for (a) but performed with the remaining carvedilol structures available in the literature. [See Comment for definitions of structures (II), (III), (IV) and (V).] |
