Structural transformation is important for the study of silver cluster compounds, in which controlled synthesis of their shapes and sizes via anion template-driven is one key scientific question. In this work, the CO32- anion templates were captured by the [ t BuC≡CAg] n system under the stimulation induced by carboxylate ligand CF3COO-/PhCOO-, and two silver alkynyl clusters [(CO32-)@Ag21( t BuC≡C)16(CF3COO)3(H2O)]·DMF·2CH2Cl2 (1) and [(CO32-)2@Ag24( t BuC≡C)16(PhCOO)4]·CH3OH·4DMF (2) have been successfully isolated and charactered. With the increase of the number of CO32- templates from single to double, the outer silver atoms from twenty-one to twenty-four, accompanied by the growth of the cluster skeleton from 9.8 Å × 6.9 Å of the (CO32-)@Ag21 unit to 10.5 Å × 7.3 Å of the (CO32-)2@Ag24 unit. In addition, the syntheses, structures, photocurrent responses, cyclic voltammetry characteristics, luminescence, and photodegradation of compounds 1 and 2 have been studied.
