Ca3W crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded in a distorted see-saw-like geometry to four equivalent W(1) atoms. W(1) is bonded to twelve equivalent Ca(1) atoms to form a mixture of face and corner-sharing WCa12 cuboctahedra.
Ca3W crystallizes in the hexagonal P6_3/mmc space group. Ca(1) is bonded in a distorted see-saw-like geometry to four equivalent W(1) atoms. There are two shorter (3.30 Å) and two longer (3.54 Å) Ca(1)-W(1) bond lengths. W(1) is bonded to twelve equivalent Ca(1) atoms to form a mixture of face and corner-sharing WCa12 cuboctahedra.
