Ni Ag B B
NiAgB2 crystallizes in the monoclinic Pm space group. Ni(1) is bonded in a 1-coordinate geometry to one Ag(1) and four equivalent B(1) atoms. The Ni(1)-Ag(1) bond length is 1.19 Å. There are two shorter (2.18 Å) and two longer (2.57 Å) Ni(1)-B(1) bond lengths. Ag(1) is bonded in a 1-coordinate geometry to one Ni(1) and four equivalent B(1) atoms. There are two shorter (2.18 Å) and two longer (2.57 Å) Ag(1)-B(1) bond lengths. B(1) is bonded in a 5-coordinate geometry to two equivalent Ni(1), two equivalent Ag(1), and one B(1) atom. The B(1)-B(1) bond length is 1.05 Å.
