Materials Data on K3Nb by Materials Project
K3Nb is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. K is bonded in a 4-coordinate geometry to four equivalent Nb atoms. There are two shorter (3.99 Å) and two longer (4.15 Å) K–Nb bond lengths. Nb is bonded to twelve equivalent K atoms to form a mixture of face and corner-sharing NbK12 cuboctahedra.
