Compound <jats:bold>1<\/jats:bold> has a hybrid sheet with neutral zinc\u2010phosphite chains as supramolecular building blocks (SBBs), whereas <jats:bold>2<\/jats:bold> exhibits a 3D hybrid architecture with other neutral zincophosphite chains as supramolecular building blocks. The structural discrepancy between <jats:bold>1<\/jats:bold> and <jats:bold>2<\/jats:bold> is mainly due to the distinct linkage modes between organic TIPA ligands and inorganic zincophosphite chains. Interestingly, compounds\u2005<jats:bold>1<\/jats:bold> and <jats:bold>2<\/jats:bold> feature fast photochromism in response to UV light irradiation under ambient conditions. The discrepancy of photochromic performance between <jats:bold>1<\/jats:bold> and <jats:bold>2<\/jats:bold> is mainly due to the different geometrical configuration of the TIPA ligand. Different to majority of reported hybrid photochromic compounds driven by photochromic active units, the photochromism in <jats:bold>1<\/jats:bold> and <jats:bold>2<\/jats:bold> is derived from the electron transfer (ET) between phosphite and non\u2010photochromic triimidazole\u2010derivative ligand TIPA. Compared with the widely explored nonphotochromic polypyridine\u2010derivative as electron acceptors (EAs), our work provides a new EA model for the design of hybrid photochromic materials based on the ligand\u2010to\u2010ligand ET mechanism.
