Nd F
NdF is Tetraauricupride structured and crystallizes in the monoclinic Cm space group. Nd(1) is bonded in a distorted body-centered cubic geometry to eight equivalent F(1) atoms. There are a spread of Nd(1)-F(1) bond distances ranging from 2.43-2.93 Å. F(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Nd(1) atoms.
