We report the synthesis and structures of two 34-atom metal nanoclusters, namely [Ag 34 (BTCA) 3 (CCBu t ) 9 (tfa) 4 (CH 3 OH) 3 ]SbF 6 and [AuAg 33 (BTCA) 3 (CCBu t ) 9 (tfa) 4 (CH 3 OH) 3 ]SbF 6 , where H 4 BTCA is p-tert -butylthiacalix[4]arene and tfa is trifluoroacetate. Their compositions an...
