Tetraiodonickelate(II) is a complex ion of nickel with four iodide ions [NiI 4] 2− arranged in a tetrahedron. [1] [NiI 4] 2− is red in solution. This colour is due to absorption around 530 nm and below 450 nm. Maximum light transmission is around 620 nm, which is red. A broad weak absorption in the near infrared is at 740 nm. [1]
Form 4 is a United States SEC filing that relates to insider trading.Every director, officer and owner of more than 10 percent of a class of a particular company's equity securities registered under Section 12 of the Securities Exchange Act of 1934 must file with the United States Securities and Exchange Commission a statement of ownership regarding such security.
The [Ni(CN) 4] 2-anions are arranged in a columnar structure with Ni---Ni distances of 4.294 Å, which is well beyond the sum of the van der Waals radius of the nickel cation. [1] This columnar structure resembles those of the other [M(CN) 4 ] 2- anions of the heavy congeners of the group 10 metals (M = Pd, Pt).

Manganese(II) nitrate is prepared from manganese dioxide and nitrogen dioxide: [1]. MnO 2 + 2 NO 2 + 4 H 2 O → Mn(H 2 O) 4 (NO 3) 2. In this redox reaction, two moles of the reductant NO 2 (gas) donate each one electron to MnO 2 (black solid), the oxidant, which is reduced from its oxidation state (IV) to its lower state (II).
