Zusammenfassung:
Two organoantimony (V) coordination complexes, namely Ph3Sb(2-tmbc) (1)
and Ph3Sb(3-tmbc) (2) (2-tmbc = 2-(trifluoromethyl)benzoic carboxyl,
3-tmbc = 3-(trifluoromethyl)benzoic carboxyl) have been synthesized and
characterized by IR spectra, elemental analysis, powder X-ray
diffraction (PXRD) and single-crystal X-ray diffraction. Single-crystal
X-ray diffraction analysis reveals that complexes 1 and 2 show different
architectures by the intermolecular hydrogen bonds (C-H center dot
center dot center dot F), complex 1 displays an 1D straight chain
structure, while complex 2 shows an 1D zigzag chain structure. The
photodegradation properties of complexes 1 and 2 has been investigated
in organic dyes (RhB, MV, MB) the results indicated that the two
complexes are good candidates for the photocatalytic degradation of
three dyes. The tentative photocatalytic degradations mechanism is
discussed. (C) 2017 Elsevier B.V. All rights reserved.
