| Abstract: A complex [Mn(NCS)2(Eim)4] (where Eim=1-ethylimidazole) has been synthesized and structurally cha-racterized by X-ray diffraction single-crystal structure analysis. The compound crystallizes in the Orthorhombic space group Pbca with the cell parameters: a=1.618 9(3) nm, b=1.787 4(4) nm, c=1.999 4(4) nm, and V=5.786(2) nm3, Z=8. In the structure, each Mn atom is coordinated by four Eim ligands and a pair of monodentate isothiocyanic groups, affording a compressed octahedral MnN6 core. The NCS- anions are trans and four N atoms from the Eim ligands define the equatorial plane. The C-H…π supramolecular interactions between C-H and imidazole rings of Eim link the molecules into independent chains running along the c-axis. The thermal gravity(TG) data indicates that thermal decomposition of the title complex takes place in two steps, the residue is Fe. CCDC: 646113. |
