Two iodoargentate hybrids, {[HNOM][AgI2]·H2O} (1) and {[HINOM][AgI2]·H2O} (2) (HNOM+ = N-protonated 3-carbomethoxypyridinium; HINOM+ = N-protonated 4-carbomethoxypyridinium), were designed and prepared, which were constructed from typical [AgI2]- inorganic chains and cationic H-bonding supramol. networks (1-dimensional for 1 and three-dimensional for 2) of lattice H2O and positional isomeric N-protonated carbomethoxypyridinium. Two hybrids exhibit sensitive photochromism based on intermol. electron transfer (ET) and thermochromism due to reversible hydration and dehydration and the consequent variation of intermol. charge transfer (CT). Also, loss of lattice H2O gives rise to improved photochromic dehydrated form 1T and optically inert dehydrated form 2T, suggesting a delicate modulating effect of lattice contraction on the intermol. CT and ET as well as consequently photoresponsive behaviors.
