scandiobabingtonite is in the triclinic crystal system, with space group p1. the unit cell dimensions are a=7.536(2) å, b=11.734(2) å, c=6.748(2) å, α=91.70(2)°, β=93.86(2)°, γ=104.53(2)°. these dimensions are almost identical to those of babingtonite. the difference in dimensions is caused by the replacement of iron with scandium in the fe-centered octahedra. the fe-o distance measures as 2.048 å, while the sc-o distance is 2.092 å. this equates to a slightly larger octahedra in scandiobabingtonite than babingtonite.
