Mass spectrometry guided surface modification of a tellurate ion templated 36-nucleus silver alkynyl nanocluster

Under the guidance of the ESI-MS result for [TeO 6 @Ag 36 (CC t Bu) 18 (tfa) 12 ] (1, tfa = trifluoroacetate), a new 36-nucleus silver-alkynyl cluster substituted by four pentafluorobenzoates, named as [TeO 6 @Ag 36 (CC t Bu) 18 (tfa) 8 (F 5 PhCO 2 ) 4 ] (2), has been fabricated.
