Summary: New Zn(II) and Cd(II) coordination polymers were synthesized using a novel ligand and naphthalene-1,4-dicarboxylic acid, displaying 2D and 3D structures. Both complexes exhibited luminescent properties, with complex 2 showing high sensitivity towards Fe3+ ions. The quenching effect is likely due to interactions between metal ions and amide carbonyl oxygen atoms.

Summary: A search in the Cambridge Structural Database was conducted for pyridyl-substituted dithiocarbamate ligands, identifying 73 different structures. While transition metal dithiocarbamates showed similar structures to their non-pyridyl derivatives, main group element dithiocarbamates exhibited a more significant role for coordination of the pyridyl-nitrogen atoms.

Summary: The C-2-symmetric photochromic molecule 3, with dithienylethene (DTE) and ferrocene units connected by an alkyne bridge, binds with Hg2+ where the open state (3o) binds more strongly than the closed state (3c). The metal binding does not disrupt the inherent photoisomerization properties of the DTE core, and the photoswitchability persists even in the metal-coordinated form of 3, albeit at a slower rate.
