NbCo3 is beta Cu3Ti-like structured and crystallizes in the hexagonal P6_3/mmc space group. Nb(1) is bonded to twelve equivalent Co(1) atoms to form NbCo12 cuboctahedra that share corners with six equivalent Nb(1)Co12 cuboctahedra, corners with twelve equivalent Co(1)Nb4Co8 cuboctahedra, edges with eighteen equivalent Co(1)Nb4Co8 cuboctahedra, faces with eight equivalent Nb(1)Co12 cuboctahedra, and faces with twelve equivalent Co(1)Nb4Co8 cuboctahedra. Co(1) is bonded to four equivalent Nb(1) and eight equivalent Co(1) atoms to form distorted CoNb4Co8 cuboctahedra that share corners with four equivalent Nb(1)Co12 cuboctahedra, corners with fourteen equivalent Co(1)Nb4Co8 cuboctahedra, edges with six equivalent Nb(1)Co12 cuboctahedra, edges with twelve equivalent Co(1)Nb4Co8 cuboctahedra, faces with four equivalent Nb(1)Co12 cuboctahedra, and faces with sixteen equivalent Co(1)Nb4Co8 cuboctahedra.

There are six shorter (2.57 Å) and six longer (2.59 Å) Nb(1)-Co(1) bond lengths. Co(1) is bonded to four equivalent Nb(1) and eight equivalent Co(1) atoms to form distorted CoNb4Co8 cuboctahedra that share corners with four equivalent Nb(1)Co12 cuboctahedra, corners with fourteen equivalent Co(1)Nb4Co8 cuboctahedra, edges with six equivalent Nb(1)Co12 cuboctahedra, edges with twelve equivalent Co(1)Nb4Co8 cuboctahedra, faces with four equivalent Nb(1)Co12 cuboctahedra, and faces with sixteen equivalent Co(1)Nb4Co8 cuboctahedra. There are a spread of Co(1)-Co(1) bond distances ranging from 2.42-2.72 Å.
