The pyrazine in (pz)2Pt(mnt) (pz = pyrazine, mnt = maleonitriledithiolate) was exchanged with bispyridyl ligands (1,2-Bis(4-pyridyl)ethane, bpa, 1,2-Bis(4-pyridyl)ethylene, bpe, 1,2-Bis(4pyridyl)propane, bpp, and 1,2-Bis(4-pyridylamido)benzene, bpab) to form supramolecular building blocks. The ratio of ligand to Pt(mnt) determined the manner of coordination (monotopic or bridging) of the bispyridyl ligands. All compounds exhibited strong absorption into the visible region.
