Synthesis and Structural Features of Co(II) Compounds with 3-Arylidene-1-pyrrolidine Derivatives and Monocarboxylic Acid Anions

A series of cobalt(II) acetate and trifluoroacetate compounds with 3-arylidene-1-pyrroline derivatives (X-L; X = Cl, OH) as N-donor ligands were synthesized. The variation of reaction and crystallization conditions resulted in the isolation of coordination compounds with various compositions and structures: tetranuclear complexes based on the {Co₄(OH)₄}^4– cubane moiety, [Co₄(OH)₄(Cl-L)₄(OAc)₄] (I), 1D polymer [Co(H₂O)(Cl-L)₂(CF₃COO)_1.167(OAc)_0.833]_n (II), and molecular complex [Co(OH-L)₂(OAc)₂] (III). The products were characterized by X-ray diffraction, IR spectroscopy, and CHN analysis. The structure and crystal packing in the obtained complexes were analyzed in detail, the main structuring non-covalent interactions in the crystals were identified.
