Buy Structure and Bonding: Nitrosyl Complexes in Inorganic Chemistry, Biochemistry and Medicine I (Series #153) (Hardcover) at Walmart.com 5C5H5)3 (μ2-NO)3 (μ3-NO)], three NO groups bridge two metal centres and one NO group bridge to all three.[2]. It has C3v symmetry. Inorg. Feltham. An important reaction is the acid/base equilibrium: This equilibrium serves to confirm that the linear nitrosyl ligand is, formally, NO+, with nitrogen in the oxidation state +3. Here we report an analysis of periodic trends in structure (solid, solution, and computations), bonding, and reactivity based on systematic variation of the central element (P, As, Sb, or Bi) with retention of a single tridentate triamide substituent.
