Single crystal X-ray diffraction gave the following information s: How can I explain these results ?

(1) Content : C38H36Fe2N402S4( two mole i.e. dimer of C19H19FeN20S2)
(2) A no. of atoms has to be found in the E-map such that the sum of site occupancies (occ.) is equal to 12.500 .
(3) Fused rings found in the E-map .
(4) Remarkable deviations (of displacive type ) from ideal pseudotranslational symmetry are present .
(5) No. of atoms in asymmetric unit =12.5
(6) Equivalent no. of equal atoms in primitive cell =18.
