Abstract

Abstract : An unusual crossed dimer motif is present in the solid state in the infinite TCNQ˙ − columns of the bis-12-crown-4 complexes of Li and NaTCNQ. Abstract : An investigation of the solid-state behaviour of five 12-crown-4 alkali metal TCNQ complexes, (12-crown-4)2 LiTCNQ (1 ), (12-crown-4)2 NaTCNQ (2 ), (12-crown-4)2 Li(TCNQ)2 (3 ), (12-crown-4)2 Na(TCNQ)2 (4 ), and (12-crown-4)2 K(TCNQ)2 (5 ), reveals an unusual " cross-stitch " packing motif with the extended face-to-face π-stacked TCNQ˙ − columns present in complexes 1 and 2 . The effect of the presence of additional neutral TCNQ 0 has also been explored.
