Abstract
Hexamethylbipyrazine-N,N',N ",N'''-tetraoxide (1) is synthesized in racemic form and cocrystallized with tetracyanoethylene to give a donor-acceptor ( DA) networked lattice, The resulting DA(2) cocrystal contains homochiral 2- D DA arrays (layers) cohered by 2.7 Angstrom NO ... C=C DA bonds with perip lanar O p-orbital/C=C orientations, Layer formation is stereoselective, whi le interlayer relations yield a racemic lattice.
