| Popis: | Syntheses, structures, and magnetic properties of one mononuclear inclusion compound [CuIIL1⊂(H2O)] (1) and three tetrametal systems of the composition [{CuIIL1}2{CuIIL1MII(H2O)3}](ClO4)2(M = Cu (2), M = Co (3), M = Mn (4)) derived from the hexadentate Schiff base compartmental ligand N,N‘-ethylenebis(3-ethoxysalicylaldimine) (H2L1) have been described. Compounds 1 and 2 crystallize in orthorhombic Pbcn and monoclinic P21/c systems, respectively, and the space group of the isomorphous compounds 3 and 4 is monoclinic C2/c. The water molecule in 1 is encapsulated in the vacant O4 compartment because of the hydrogen bonding interactions with the ether and phenolate oxygens, resulting in the formation of an inclusion product. The structures of 2−4 consist of the [CuIIL1MII(H2O)3]2+ cation and two mononuclear [CuIIL1] moieties. In the dinuclear [CuIIL1MII(H2O)3]2+ cation, the metal centers are doubly bridged by the two phenolate oxygens. The second metal center, MII (Cu in 2, Co in 3, and Mn in 4), in the [CuI... |
