| Abstract: | A number of complexes M(4-MePy)n (NCS)2], where M=Co(II), Ni(II), Zn(II), Cd(II); n=2 or 4 have been synthesized and phase diagrams M(4-MePy)2(NCS)2]-4-MePy have been studied. The forming compounds have been obtained and described with the help of IR-spectroscopy and thermal analysis. The structure of a molecular type with variable section channels, filled by two types guest-molecules (by a water molecule in the narrow part of the channel and by two 4-methylpyridine molecules in the broad part of the channel, with a total ratio guest: host being 1:1) for Cd(4-MePy)4 (NCS)2]·0.67(4-MePy)·0.33H2O has been defined by X-ray method. This clathrate is isostructural (X-ray powder diffractogram) to the anhydrous compound Cd(4-MePy)4 (NCS)2]·0.67(4-MePy). |
