Q. Write the IUPAC name of the compound $K_2[Cr(NO)(CN)_4(NH_3)]$ . Spin magnetic moment of the complex $\mu =1.73 \,BM . $ Give the structure of anion.

IIT JEEIIT JEE 2003Coordination Compounds

Solution:

The spin-only magnetic moment $(\mu ) $ of the complex is $1.73\, BM$.
It indicates that nucleus of complex, chromium ion has one unpaired electron. So, the ligand NO is unit positively charged.
$K_2[Cr(NO)(CN)_4(NH_3)]$
