This investigation confirms that silver stearate consists of an infinite‐sheet, two‐dimensional, nonmolecular layered structure. Scanning electron microscopy, X‐ray diffraction, and infrared spectroscopy reveal the following: plate‐like morphology is identified from the SEM image, XRD peaks can be indexed to the (0 k 0) reflections of a layered structure, and infrared peaks show that alkyl chains are present in an all‐trans conformational state with little or no significant gauche population. Based on these structural characteristics, we demonstrate that silver stearate, a prototype of layered organic‐inorganic hybrid material, can be grown not only in a designed two‐dimensional pattern but also in three‐dimensionally ordered ways by using carboxyl‐group terminated nanoparticles as a template.
