Topochemical modification of layered perovskites by microwave-assisted methods allows for the rapid introduction of organic substituents to produce inorganic-organic hybrid materials. Functionalization of the interlayer space of the perovskite lamellar structures can form interstratified inorganic and organic layers, which in turn can be utilized to tune the interlayer spacing, content, and, correspondingly, the properties of the final hybrid compounds. In this study, grafting reactions with 4-hydroxy-4-biphenyl carboxylic acid, 3,5-dihydroxy benzoic acid, 4-hydroxybenzoic acid and 5-hydroxyisophthalic acid, on HLaNb<sub>2</sub>O<sub>7</sub> and its derivatives were investigated via a microwave-assisted method. The obtained products were analyzed with X-ray diffraction, thermogravimetric analysis, and Raman spectroscopy. Details on the synthesis and structures of various new inorganic-organic hybrids will be presented and the influence of the different molecular components discussed.
