The synthesis of H 3 [Bi(SCN) 6 ] was adapted from Ref. 20. Bi 2 O 2 (CO 3 ) (0.50 g, 0.98 mmol) was suspended in ca. 12 mL H 2 O followed by the addition of the HSCN/ether solution. The resulting reaction mixture was stirred vigorously under a slight flow of N 2 until all ether had been removed and the solution had turned bright orange. Any remaining solids were filtered off and the orange solution was placed under a slight vacuum to remove any excess HSCN. A portion of the the H 3 [Bi(SCN) 6 ] solution was left to evaporate yielding large, yellow, crystals of Bi(NCS) 3 .
