Parameter	Value	Mean deviation
Radius (with respect to Mg-atoms - z-axis)	22.75 Å	±0.6 Å (along x-axis)
		±0.7 Å (along y-axis)
Distance between chlorins in stacks (Mg-Mg distance; along z-axis in a stack)	6.4 Å	±0.2 Å
Shift between neighbors stacks along z-axis	2.16 Å	±0.16 Å
Angle* between transition dipole moment vector and symmetry axis (α)	36.5°	±1.5°
Angle* between transition dipole moment vector and radius-vector connecting Mg-atom and z-axis (β)	280°	±4.3°
Number of stacks per rod aggregate	18	–

^*The angle definitions correspond to those in a spherical coordinate system which the z-axis coinciding with the symmetry axis of the aggregate (z-axis).
