Dithiolene based coordination polymers, due to their coordinative bonds with covalent character, feature interesting electrical properties. We present the syntheses and crystal structures of three coordination polymers based on the ligand 2,3‐pyrazinedithiolate (pdt 2− ) and Ag + and Zn 2+ ions. 2D [Ag 3 (Hpdt) 2 ](ClO 4 ) ( 1 ) and Cs 1D [Ag(pdt)] ⋅ CH 3 OH ( 2 ) feature short Ag⋅⋅⋅Ag distances, 3D [Zn(pdt)] ( 3 ) has a 3D network structure and is stable up to 480 °C. The optical band gaps of the three coordination polymers are within the visible range of the electromagnetic spectrum. The coordination polymer 1 has the smallest bandgap of 1.8 eV, 2 and 3 , with the fully deprotonated ligand, exhibit wider bandgaps of 2.5 and 2.7 eV, respectively.
