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.
