Abstract

Ni2MnGa is alpha iridium vanadium-derived structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are three inequivalent Mn sites. In the first Mn site, Mn is bonded in a 8-coordinate geometry to eight Ni and three equivalent Ga atoms. There are four shorter (2.48 Å) and four longer (2.51 Å) Mn–Ni bond lengths. There are one shorter (2.70 Å) and two longer (2.76 Å) Mn–Ga bond lengths. In the second Mn site, Mn is bonded in a distorted body-centered cubic geometry to eight Ni and three Ga atoms. There are a spread of Mn–Ni bond distances ranging from 2.48–2.51 Å. There are a spread of Mn–Ga bond distances ranging from 2.78–2.95 Å. In the third Mn site, Mn is bonded in a distorted body-centered cubic geometry to eight Ni and two equivalent Ga atoms. All Mn–Ni bond lengths are 2.49 Å. Both Mn–Ga bond lengths are 2.76 Å. There are three inequivalent Ni sites. In the first Ni site, Ni is bonded in a distorted body-centered cubic geometry to four Mn and four Ga atoms. There are two shorter (2.48 Å) and two longer (2.51 Å) Ni–Ga bond lengths. In the second Ni site, Nimore »« less
