Abstract

The structure of a plate crystal of ((PMe₄⁺·TCNQF₄ ^-.)·1/2TCNQF₄) was analyzed and very similar to that of the corresponding NMe₄⁺ salt. However, significant difference was recognized between the two crystals in the structures of TCNQF₄ and TCNQF₄^-. molecules, and especially in the contacts between the two TCNQF₄^-. molecules in dimerization and between the TCNQF₄ and TCNQF₄^-. molecules. The change in both molecular structure and contact as above was also observed at a lowering temperature. The magnitude in change was larger in the NMe₄⁺ salt than in the PMe₄⁺ salt. However, the change exerted no special influence on the elctrical conducting and magnetic properties.
