the type [E(CN)(n)(-)] x [B(C(6)F(5))(3)](n): E = N (dca_nb with n = 1, 2; b = B(C(6)F(5))(3)); E = C (tcm_nb with n = 1, 2, 3), and E = B (tcb_nb with n = 1, 2, 3, 4). Salts bearing these anions such as B[(CN) x B(C(6)F(5))(3)](4)(-) (= [B(CN)(4)(-)] x [B(C(6)F(5))(3)](4)), C[(CN) x B(C(6)F(5))(3)](3)(-) (= [C(CN)(3)(-)] x [B(C(6)F(5))(3)](3)), and N[(CN) x B(C(6)F(5))(3)](2)(-) (=[N(CN)(2)(-)] x [B(C(6)F(5))(3)](2))
将二氰胺 (dca)、三氰基甲烷 (tcm) 和四氰基硼酸盐 (tcb) 的碱金属盐或银盐添加到 B(C(6)F(5))(3) 的乙醚溶液中,得到含有大量 B( [E(CN)(n)(-)] x [B(C(6)F(5))(3)](n) 类型的 C(6)F(5))(3) 加合阴离子: E = N (dca_nb 与 n = 1, 2; b = B(C(6)F(5))(3)); E = C(tcm_nb,n = 1, 2, 3),E = B(tcb_nb,n = 1, 2, 3, 4)。带有这些阴离子的盐,例如 B[(CN) x B(C(6)F(5))(3)](4)(-) (= [B(CN)(4)(-)] x [B (C(6)F(5))(3)](4)), C[(CN) x B(C(6)F(5))(3)](3)(-) (= [C (CN)(3)(-)] x [B(C(6)F(5))(3)](3))
