A Chiral 2-D Donor−Acceptor Array of a Bipyrazine N-Oxide and Tetracyanoethylene
摘要:
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 periplanar O p-orbital/C=C orientations, Layer formation is stereoselective, while interlayer relations yield a racemic lattice.
