Herein the guest inclusions and interactions in a binary (cyclopentanemethanol + CH4) hydrate were explored via 13C NMR spectroscopy and XRD analysis. The 13C NMR spectra of the binary (cyclopentanemethanol + CH4) hydrate confirmed the formation of structure II hydrate with the inclusion of cyclopentanemethanol and CH4 in the structure II hydrate cages. Rietveld analysis on XRD profiles of the binary (cyclopentanemethanol + CH4) hydrate confirmed the formation of a cubic Fd3m hydrate and the possible host-guest interactions. Finally, the thermodynamic stability of the binary (cyclopentanemethanol + CH4) hydrate was relatively stable than that of the pure methane hydrate.
