Slight ligand modifications within multitopic linear hydroxamates promotes connectivity differences in Cu(II) 1-D coordination polymers
Two novel hydroxamic acids have been used in constructing two 1-D coordination polymers. Slight structural differences promote connectivity changes upon Cu(II) metalation as rationalised using DFT calculations and Hirschfeld surface analysis.

TIPA-ligand-based luminescent Cd(II) organic frameworks as an outstanding sensor for detecting Fe3+ in an aqueous medium
Two new Cd-based LMOFs (MOF-1 and MOF-2) were prepared with good photoluminescence properties. MOF-2 exhibits high sensitivity in detecting Fe3+ with a very large quenching coefficient of 27 027 M−1. It has potential application in the chemical sensing of CrO42− and Cr2O72−.
