WebThe IUPAC name of the compound [Ni(DMG) 2] is Bis(dimethylglyoximato)nickel(II). The prefix Bis indicates two. The ligand is named as dimethylglyoximato. The oxidation state is written in roman numerals in parenthesis. Since the molecule is neutral, the name of the metal is written as nickel and not as nickelate. Thus option C is correct. WebA bulk modulus of Ni(dmg) 2 is obtained from the volume versus pressure curve fitted by a Birch equation of state. A Ni–Ni distance along the c-axis abruptly decreases from 3.255 Å at ambient pressure to 2.82 Å at 7.4 GPa. However, the lattice constant along the b-axis is smaller than that along the a-axis at pressures greater than 6 GPa.
