Two organic-inorganic hybrids, [3-H2DPNDI]-[ZnCl4]center dot 0.5H(2)O (1) and [4-H2DPNDI][ZnCl4]center dot 0.5H(2)O (2) (3-H2DPNDI2+ = protonated N,N-di(3-pyridyl)-1,4,5,8-naphthalene diimide, 4-H2DPNDI2+ = protonated N,N-di(4-pyridyl)-1,4,5,8-naphthalene diimide), have been designed and 'prepared. Compounds 1 and 2 are constructed from typical [ZnCl4](2- )inorganic clusters and positional isomeric organic cations of [H2DPNDI](2+), which are assembled into different three-dimensional supramolecular networks via different anion-pi interactions and hydrogen-bonding interactions. Photochromism of 1 and non-photochromism of 2 are attributable to the usage of positional isomers, which leads to the different spatial stack of [ZnCl4](2-) donors and [H2DPNDI](2+) acceptors, suggesting a delicate modulating effect of the distinct interfacial contacts on the intermolecular charge transfer/electron transfer and consequently photoresponsive behaviors.
