Ti3Ga is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Ti(1) is bonded to eight equivalent Ti(1) and four equivalent Ga(1) atoms to form distorted TiTi8Ga4 cuboctahedra that share corners with four equivalent Ga(1)Ti12 cuboctahedra, corners with fourteen equivalent Ti(1)Ti8Ga4 cuboctahedra, edges with six equivalent Ga(1)Ti12 cuboctahedra, edges with twelve equivalent Ti(1)Ti8Ga4 cuboctahedra, faces with four equivalent Ga(1)Ti12 cuboctahedra, and faces with sixteen equivalent Ti(1)Ti8Ga4 cuboctahedra. Ga(1) is bonded to twelve equivalent Ti(1) atoms to form GaTi12 cuboctahedra that share corners with six equivalent Ga(1)Ti12 cuboctahedra, corners with twelve equivalent Ti(1)Ti8Ga4 cuboctahedra, edges with eighteen equivalent Ti(1)Ti8Ga4 cuboctahedra, faces with eight equivalent Ga(1)Ti12 cuboctahedra, and faces with twelve equivalent Ti(1)Ti8Ga4 cuboctahedra.

There are a spread of Ti(1)-Ti(1) bond distances ranging from 2.78-2.91 Å. There are two shorter (2.81 Å) and two longer (2.84 Å) Ti(1)-Ga(1) bond lengths. Ga(1) is bonded to twelve equivalent Ti(1) atoms to form GaTi12 cuboctahedra that share corners with six equivalent Ga(1)Ti12 cuboctahedra, corners with twelve equivalent Ti(1)Ti8Ga4 cuboctahedra, edges with eighteen equivalent Ti(1)Ti8Ga4 cuboctahedra, faces with eight equivalent Ga(1)Ti12 cuboctahedra, and faces with twelve equivalent Ti(1)Ti8Ga4 cuboctahedra.
