“…Tetrathiometallate anions [MS 4 ] 2À (M = Mo, W) and their clusters with various transition metals are well documented owing to their rich coordination chemistry [1][2][3][4][5][6][7][8][9][10][11][12], their relations to industrial catalysis process [13][14][15], biological systems [16][17][18][19], and photonic materials [20,21]. It is noteworthy that the Mo(W)/Cu(Ag)/S clusters, especially those containing pyridine and its derivatives, e.g.…”
