Vww. Yam et al., Synthesis, structural characterization and binding studies of a novel dinuclear gold(I) calix[4]crown acetylide complex, CHEM COMMUN, (16), 2000, pp. 1513-1514
A novel dinuclear gold(I) calix[4]crown acetylide complex, [Au(PPh3)](2)L,
has been synthesized and structurally characterized; binding studies of the
complex revealed a high K+/Na+ selectivity.
