Abstract: | Complexes RbL (I) and Li2(C2H5OH)L2] (II) (L = C23H15O3) have been synthesized and their crystal structures have been studied. Both compounds have monoclinic crystals with space group P21/c and Z = 4; I: a = 11.632(2) Å, b = 15.154(3) Å, c = 11.457(2) Å, β = 104.34(3)°; II: a = 12.982(3)Å, b = 12.083(2) Å, c = 25.317(5) Å β = 100.11(3)°. In the structure of I, dimeric groups Rb2O6] with a shared edge are linked by the ligands to give infinite layers perpendicular to the x axis and cavities that form oblong channels. In the structure of II, Li2O7 dimers are formed by vertex sharing. The coordination of one of the lithium atoms (Li(1)) is completed to tetrahedral by the oxygen atom of the ethanol molecule. The structure of II, like that of I, is layered. |
