Capped-stick representations for the two searches in the CSD (see Table 4[link]) (MercuryCSD; Macrae et al., 2008BB16). Search A: 2-PD derivatives, with C atoms designated `T' required to be bonded to four atoms and R = H. Examples: A1 is 2-aza­spiro­[4.5]decan-3-one; A2 is (5S*)-1-oxo-2-aza­spiro­[4.4]non-7-ene-7-carboxyl­ate; A3 is 2-pyrrolidinone monohydrate. [Symmetry codes: (i) x, y, z; (ii) x, y, z − 1; (iii) x, −y + [{1\over 2}], z − [{1\over 2}].] Search B: naphtho­lactam derivatives, any singly-bonded substituent for R, no cocrystals. Examples: B1 is 7-amino-6,8-bis­(4-meth­oxy­phen­yl)benz[cd]indol-2(1H)-one; B2 is 6-(4-bromo­phen­yl)-1-methyl­benz[cd]indol-2-one; B3 is S-benzyl 2-oxobenzo[cd]indole-1(2H)-carbothio­ate.
