In this research, the organic salt [RCOOH] Br with long alkyl-chain was synthesized, and the organophilic [RCOOH]-Montmorillonite was formed by cation-exchange-reaction between Na-Montmorillonite and synthesized organic salt [RCOOH] Br. After drying of the organophilic [RCOOH]-Montmorillonite at $65^{\circ}C$ in high vaccum, the experiments for the probability of forming its complexes with various swelling-solutions as dist, water, methanol, ethanol, acetonitrile, propionitrile, butyronitrile, toluene and n-decanol were performed, and the corresponding basal spacings obtained were 17.44$\AA$, 31.86$\AA$, 34.38$\AA$, 30.37$\AA$, 32.39$\AA$, 35.04$\AA$, 14.16$\AA$ and 14.63$\AA$ respectively.
