Abstract
A new square-shaped Zn(II) complex, namely, [Zn4(L)4(phen)4]?6H2O (1) (L =
2-hydroxynicotinate and phen = 1,10- phenanthroline), has been synthesized
under hydrothermal condition. The crystal of 1 belongs to triclinic, space
group P -1 with a = 10.773(2) ?, b = 12.641(3) ?, c = 13.573(3) ?, ? =
107.44(3)?, ? = 102.66(3)?, ? = 93.89(3)?, C72H56N12O18Zn4, Mr = 1638.77, V =
1702.8(6) ?3 , Z = 1, Dc = 1.598 g/cm3 , S = 1.045, ?(MoK?) = 1.475 mm-1 ,
F(000) = 836, R = 0.0472 and wR = 0.0919. In 1, four L ligands bridge four
Zn(II) atoms to form a square-shaped structure, where four phen ligands are
respectively located on four corners of the square. The ?-? stacking
interactions extend the adjacent squares into a 1D supramolecular chain. The
thermal behavior of 1 has been characterized. Moreover, its solid state
luminescence property has been studied at room temperature.
