NO is nitrogen monoxide or nitric oxide. CN- is cyanide ion
The compound Cr(CN)₃ is called chromium(III) cyanide. It consists of chromium in the +3 oxidation state coordinated with three cyanide ions (CN⁻). This compound is part of a class of coordination complexes that involve transition metals and ligands.
Any negatively charged species that is able to donate its lone pair to the metal is called a negative ligand. For example, Cl- , Br-, SO4-2, C2O4-2. The name of the ligand will end with O (i.e. sulphate will become sulphato, nitrite will become nitrito etc.)
The spectrochemical series ranks ligands based on their ability to produce a strong ligand field in coordination complexes. Strong ligands create a large energy gap between the eg and t2g orbitals, leading to low-spin complexes with paired electrons in the eg orbitals. Ligands at one end of the series, such as CN- and CO, are considered strong field ligands, while ligands at the other end, like F- and H2O, are weak field ligands.
If you're referring to LDAP, CN = common name
