Two photochromic methylated nicotinohydrazide iodoargentate hybrids†
Abstract
Directed by in situ methylated nicotinohydrazide (MNH2+), two iodoargentate hybrids, {[MNH][Ag3I5]}n (1) and {[MNH][Ag7I9]}n (2), have been synthesized via modulating the organic/inorganic ratio. They exhibit rare structure-dependent electron transfer (ET) photochromism as confirmed by EPR, XPS, and UV-vis absorption spectra.
