K3Ti is beta Cu3Ti-like structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to four equivalent K(2) and four equivalent Ti(1) atoms to form distorted KK4Ti4 cuboctahedra that share corners with eight equivalent K(1)K4Ti4 cuboctahedra, corners with eight equivalent K(2)K8Ti4 cuboctahedra, corners with eight equivalent Ti(1)K12 cuboctahedra, edges with four equivalent K(2)K8Ti4 cuboctahedra, edges with four equivalent Ti(1)K12 cuboctahedra, edges with twelve equivalent K(1)K4Ti4 cuboctahedra, and faces with six equivalent K(1)K4Ti4 cuboctahedra. In the second K site, K(2) is bonded to eight equivalent K(1) and four equivalent Ti(1) atoms to form distorted KK8Ti4 cuboctahedra that share corners with four equivalent K(2)K8Ti4 cuboctahedra, corners with eight equivalent Ti(1)K12 cuboctahedra, corners with sixteen equivalent K(1)K4Ti4 cuboctahedra, edges with eight equivalent K(1)K4Ti4 cuboctahedra, edges with eight equivalent K(2)K8Ti4 cuboctahedra, faces with four equivalent K(2)K8Ti4 cuboctahedra, and faces with six equivalent Ti(1)K12 cuboctahedra. Ti(1) is bonded to four equivalent K(2) and eight equivalent K(1) atoms to form TiK12 cuboctahedra that share corners with four equivalent Ti(1)K12 cuboctahedra, corners with eight equivalent K(2)K8Ti4 cuboctahedra, corners with sixteen equivalent K(1)K4Ti4 cuboctahedra, edges with eight equivalent K(1)K4Ti4 cuboctahedra, edges with eight equivalent Ti(1)K12 cuboctahedra, faces with four equivalent Ti(1)K12 cuboctahedra, and faces with six equivalent K(2)K8Ti4 cuboctahedra.
