Abstract:

The intercalation of organic guests, 2-methyl pyridine (2-picoline) and 3-methyl pyridine (3-picoline) into semiconductor layered nanomaterial (MnPS3) was investigated. New conditions were applied. New phases appeared and lattice expansions were 0.36 nm for 2-picoline intercalation and 0.728 nm for 3-picoline inter-calation. The XRD (X-ray diffraction) patterns exhibit sharp hkl rflections confirming that the material is highly crystalline. The interlayer gap (0.64 nm) of the host plays a role for the  rrangement of the guest in the interlayer region. The crystal structure of the MnPS3 was indexed in the monoclinic system before inter-calation. After intercalation, the crystal system was indexed in the trigonal unit cell. The lattice parameters were obtained and c-axis value was related to the (001) reflections.
