A chain-type diamine strategy towards strongly anisotropic triiodide of ...

Linearly bonded triiodide chains with fairly small distance between the adjacent iodine ions feature a facile electron transfer and highly anisotropic properties. Here, we demonstrate a novel strategy towards a new one-dimensional linear triiodide DMEDA·I6, using chain-type N,N′-dimethyl-ethanediamine (DMEDA) cation to coordinate triiodine ions. This …

Reclaiming Inactive Lithium with a Triiodide/Iodide Redox Couple …

A triiodide/iodide (I 3 − /I −) redox couple is introduced with a SnI 4 initiator to reclaim inactive Li. The reduction of I 3 − converts inactive Li into soluble LiI, and the oxidation of LiI by a delithiated cathode realizes the restoration of Li ion in cathode from inactive Li.

Nitơ triiodide – Wikipedia tiếng Việt

Nitơ triodide là một hợp chất vô cơ, có công thức hóa học NI3. Đây là một chất nổ cực kỳ mạnh: số lượng nhỏ phát nổ với tiếng ồn lớn, khi chạm nhẹ, tạo ra một đám mây đen của iod; nó thậm chí có thể được kích nổ bởi bức xạ alpha. NI 3 có một cấu trúc phức tạp hóa học rất khó nghiên cứu do sự không ổn định của các dẫn xuất.

What is the Difference Between Iodide and Triiodide

The term triiodide is used to name other chemical compounds containing the triiodide anion as a common name. Moreover, this term can be used for compounds that contain three iodide centres that are not bound to each other but exist as separate iodide ions. E.g. Nitrogen triiodide and phosphorous triiodide contain nitrogen and phosphorous centres, …
