“…Synthesis of Bis[μ‐{3‐thiapentanoato(2−)‐ C 5 , O ′: C 5 ′, O }]tetrakis[1‐oxopyridin‐2‐olato(1−)]disilicon(IV)−Diacetonitrile (6·2CH 3 CN): Compound 5 12 (1.00 g, 2.82 mmol) was added to a solution of 1‐hydroxy‐2‐pyridone (627 mg, 5.64 mmol) in acetonitrile (80 mL) and the mixture left undisturbed at room temperature for 42 h. The resulting crystals were isolated by filtration, washed with acetonitrile (3 × 5 mL), and dried in vacuo (10 −3 mbar, 20 °C, 12 h); yield 825 mg (1.01 mmol, 72%). M.p.…”
