Languages of Item:

Abstract:
The reactions of Al(III), Ga(III) and In(III) nitrates with 2-quinaldic
acid (qaH) afforded [Al-2(OH)(2)(qa)(4)]center dot 2H(2)O (1),
[Ga(qa)(2)(H2O)(2)]NO3 (2) and [In(qa)(2)(NO3)(H2O)] (3),
respectively, in high yields. The crystal structures of 1, 2 and 3 have
been determined by single-crystal X-ray crystallography. The structure
of 1 features a di-hydroxo bridged [Al-2(mu-OH)(2)](4+) dimer in which
each Al(III) is further ligated by two bidentate chelate qa(-) ligands.
Complexes 2 and 3 are mononuclear with the M(III) ions in octahedral
environments surrounded by two bidentate chelate qa(-) and two H2O in 2
or one H2O and a terminal NO3- in 3. Characteristic IR as well as
thermal analysis and solid-state fluorescence are discussed.
