Pj. Alonso et al., BIS(PHOSPHINE)GOLD(I) DERIVATIVES WITH 7,7',8,8'-TETRACYANOQUINODIMETHANE X-RAY STRUCTURE OF [AU(PPH3)2]TCNQ, Synthetic metals, 56(1), 1993, pp. 1772-1776
The complexes [Au(PR3)2]ClO4 (PR3 = PPh3, PPh2Me, P(p-MeC6H4)3 or P(p-
MeOC6H4)3) react with LiTCNQ to give Au(PR3)2TCNQ. The same results ar
c obtained if free TCNQ is present in the reaction mixture. The struct
ure of [Au(PPh3)2TCNQ] has been established by single-crystal X-ray di
ffraction studies and shows a short Au ... N contact of 3.21 angstrom.
