Dimeric hexakis(4-methylbenzoato)- bis(1,10-phenanthroline)didysprosium(III).

The title compound, [Dy2 (C8H7O2)6 (C12H8N2)2, forms binuclear complexes, viz. di-μ-4-methylbenzoato-Κ4O:O′-bis[bis- (4-methylbenzoato-Κ²O,O′)(1,10-phenanthroline-Κ² N,N′)-dysprosium(III)] tetra-μ-4-methylbenzoato-Κ8O:O′-bis[(4- methylbenzoato-Κ²O,O′)(1,10-phenanthroline-Κ² N,N′)dys- prosium(III)]. There are two independent binuclear complexes in the asymmetric unit, both of which are centrosym- metric. In one, the DyIII ions are linked by two bridging 4-methylbenzoate groups, while in the other, the DyIII ions are linked by four bridging 4-methylbenzoate groups. The remaining 4-methylbenzoate groups and 1,10-phenanthroline units coordinate to just one metal ion in bidentate modes. [ABSTRACT FROM AUTHOR]
