Title :   THE CRYSTAL STRUCTURE OF THE 2:1 COMPLEX OF 7,7,8,8-TETRACYANO QUINODIMETHAN AND N,N,N',N'-TETRAMETHYL-P-PHENYLENEDIAMINE, (TCNQ)2(-), TMPD(+),

Abstract : Crystals of (TCNQ)2(-), TMPD(+) are triclinic, with a = 7.782, b = 15.020, c = 6.488A, alpha = 93.52, beta = 102.77, gamma = 82.97 deg., Z = 1. The structure was deduced from a three-dimensional Patterson synthesis, and refined by block-diagonal least squares. It consists of columns of TCNQ ions which overlap in characteristic fashion. These columns are held together by TMPD ions. The average spacing between overlapping TCNQ ions is 3.24A. The bond lengths found for both ions are consistent with recently-reported data for similar complexes. (Author)
