The first metal-organic framework (MOF) of Imazethapyr and its SHG, piezoelectric and ferroelectric properties.

Hydrothermal reaction of H-Imazethapyr (2-(4,5-dihydro-4-methyl-4-(1-methylethyl)-5-oxo-1H-imidazol-2-yl)-5-ethyl-3-pyridinecarboxylic acid) with Cd(ClO4)2.6H2O offers a diamond-like MOF Cd(Imazethapyr)2 in which it crystallizes in a non-centrosymmetric space group (Fdd2) belonging to polar point group (C2v). MOF displays a strong SHG response, and good ferroelectric and piezoelectric properties.
