In 2022, Wang and co-workers reported a 2D Hofman type Fe(II)-based coordination polymer and showed that the magnetic and fluorescence properties can be synchronously tuned by various external stimuli . In the asymmetric unit of 29, two independent Fe(II) centers are present having occupancies of half (Fe1) and one (Fe2), two Pt(II) centers carrying one (Pt1) and half (Pt2) occupied atoms, six CN -and three L22 ligands (Fig. ). The Fe(II) centers were coordinated to four cyanide N atoms situated at the equatorial positions, and two N atoms from L22 ligands at the apical sites, making a distorted octahedral geometry. These Fe(II) centers were bridged through [Pd(CN)4] 2-forming a 2D molecular layer (Fig. ). The axially oriented ligands were arranged in "head to tail" fashion with adjacent ligands from the adjoining layers.
