Single crystal x-ray structure analysis revealed that at 120 K, complex 13 crystallizes in orthorhombic space group Pcca, the Fe(II) center sits in a distorted octahedral N6 coordination geometry (Fig. ). space group, and at 120 K, the average Fe-Npyridyl and Fe-Npyrazole bond distances of 1.889 Å and 1.973 Å indicate the presence of Fe(II) LS state (Fig. ). In both complexes, the short intermolecular interactions help form an extended network, i.e., a "W"-shaped plane for the complex 13 and a planar 2D network for the complex 14.
