The 61 electrons removed from the two sites around 0.5, 0.5, 0.0 and
0.5, 1.0, 0.5 would correspond to 1.5 molecules of the DMF solvent (which has
40 electrons) at each site. This suggests that three molecules of DMF per
unit cell (1.5 molecules per porphyrin unit) are entrapped in the crystal
lattice.
