%X The crystal structure of the title compound, [EtPh3P]+ [(C12H4N4)2]-, has been established by single-crystal X-ray diffraction methods at 295(1) K and refined by least squares to a residual of 0·039 for 3047 'observed' reflections. Crystals are triclinic, P&#299;, a 8 ·882(7), b 13·522(5), c 15·927(6) Å, &#945; 75·34(3), &#946; 96·69(5), &#947; 100.56(3)º, Z 2. The structure closely resembles that of the methyl-triphenyl-phosphonium and -arsonium analogues, containing tetrads of &#945;,&#945;,&#945;',&#945;'- tetracyanoquino- dimethane* molecules, the molecular planes lying parallel to each other and approximately normal to b.
