crystal data
Crystal data (from single-crystal measurements) are reported for 19 different crystalline π-molecular compounds, representing 16 different chemical species (three polymorphic pairs are included). 13 of these molecular compounds have equimolar compositions, five have donor:acceptor ratios of 1:2 and the remaining one has composition (fluorene)3 :( 1,3,5-trinitrobenzene)4.
