Ir3V is Uranium Silicide-like structured and crystallizes in the hexagonal P6_3/mmc space group. V(1) is bonded to twelve equivalent Ir(1) atoms to form VIr12 cuboctahedra that share corners with six equivalent V(1)Ir12 cuboctahedra, corners with twelve equivalent Ir(1)V4Ir8 cuboctahedra, edges with eighteen equivalent Ir(1)V4Ir8 cuboctahedra, faces with eight equivalent V(1)Ir12 cuboctahedra, and faces with twelve equivalent Ir(1)V4Ir8 cuboctahedra. Ir(1) is bonded to four equivalent V(1) and eight equivalent Ir(1) atoms to form distorted IrV4Ir8 cuboctahedra that share corners with four equivalent V(1)Ir12 cuboctahedra, corners with fourteen equivalent Ir(1)V4Ir8 cuboctahedra, edges with six equivalent V(1)Ir12 cuboctahedra, edges with twelve equivalent Ir(1)V4Ir8 cuboctahedra, faces with four equivalent V(1)Ir12 cuboctahedra, and faces with sixteen equivalent Ir(1)V4Ir8 cuboctahedra.

There are six shorter (2.67 Å) and six longer (2.72 Å) V(1)-Ir(1) bond lengths. Ir(1) is bonded to four equivalent V(1) and eight equivalent Ir(1) atoms to form distorted IrV4Ir8 cuboctahedra that share corners with four equivalent V(1)Ir12 cuboctahedra, corners with fourteen equivalent Ir(1)V4Ir8 cuboctahedra, edges with six equivalent V(1)Ir12 cuboctahedra, edges with twelve equivalent Ir(1)V4Ir8 cuboctahedra, faces with four equivalent V(1)Ir12 cuboctahedra, and faces with sixteen equivalent Ir(1)V4Ir8 cuboctahedra. There are a spread of Ir(1)-Ir(1) bond distances ranging from 2.68-2.73 Å.
