Popis: The sodium complex with 2-(diphenylacetyl)indandione-1,3 (HL) have been synthesized and studied by X-ray diffraction analysis. Crystals of [Na4(H2O)4L4] (I) precipitated from aqueous acetone are monoclinic, Z = 2, space group P21/c, a = 12.171(1) A, b = 10.527(1) A, c = 29.777(2) A, β = 97.455(1)°. The structure of compound I is based on a centrosymmetric tetranuclear [Na4O12] cage. Two central Na(2) atoms are coordinated to four O atoms of two L ligands. The central and peripheral atom polyhedrons [Na(2)O6] and [Na(1)O5] are joined by a common edge formed by two O atoms of two L ligands. Tetranuclear moieties are joined into the framework by hydrogen bonds, numerous C-H-π contacts, and π-π stacking-contacts between the conjugated and aromatic ligand systems of neighboring tetramers.
