| Popis: | Coordination compounds of iron(II) thiocyanate with tris(3,5-dimethylpyrazol-1-yl)methane (HC(3,5-Me2Pz)3), [Fe(HC(3,5-Me2Pz)3)2](NCS)2] (I) and [Fe(HC(3,5-Me2Pz)3)(Рhz)(NCS)2] · H2O (II), where Рhz is phthalazine, are synthesized. The complexes are studied by X-ray diffraction analysis, diffuse reflectance and IR spectroscopy, and static magnetic susceptibility measurements. The single crystals are obtained, and the molecular and crystal structures of complex II and compounds [Fe(HC(3,5-Me2Pz)3)(3,5-Me2Pz)(NCS)2] · С2H5OH (III), where 3,5-Me2Pz is 3,5-dimethylpyrazole, and [Fe(HC(3,5-Me2Pz)3)2][Fe(HC(3,5-Me2Pz)3)(NCS)3]2 (IV) are determined (CIF files CCDC 1415452 (II), 1415453 (III), and 1415454 (IV)). The study of the temperature dependence μeff(Т) in a range of 2–300 K shows exchange interactions of the antiferromagnetic character between the iron(II) ions in complexes I and II. |
