MnNi2Ag crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MnNi2Ag cluster. Mn(1) is bonded in a distorted water-like geometry to one Ni(1) and one Ni(2) atom. The Mn(1)-Ni(1) bond length is 1.15 Å. The Mn(1)-Ni(2) bond length is 1.19 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted single-bond geometry to one Mn(1) and one Ag(1) atom. The Ni(1)-Ag(1) bond length is 1.52 Å. In the second Ni site, Ni(2) is bonded in a single-bond geometry to one Mn(1) atom. Ag(1) is bonded in a distorted single-bond geometry to one Ni(1) atom.
