Abstract
The structure of a plate crystal of ((PMe4+.TCNQF(4)(-.)). 1/2TCNQF(4) ) was analyzed and very similar to that of the corresponding NMe4+ sal t. However, significant difference was recognized between the two crys tals in the structures of TCNQF(4) and TCNQF(4)(-.) molecules, and esp ecially in the contacts between the two TCNQF(4)(-.) molecules in dime rization and between the TCNQF(4) and TCNQF(4)(-.) molecules. The chan ge in both molecular structure and contact as above was also observed at a lowering temperature. The magnitude in change was larger in the N Me4+ salt than in the PMe4+ salt. However, the change exerted no speci al influence on the elctrical conducting and magnetic properties.
