Abstract
- A series of new metalâorganic coordination complexes, [Zn(cpds)(H2O)2]n(1), {[Zn(cpds)(4,4â²-bipy)]·6H2O}n(2), {[Zn(cpds)(bpe)]2·0.5(bpe)·4H2O}n(3), [Cu(cpds)(2,2â²-bipy)(CH3OH)]2·2H2O (4), {[Cu(cpds)(4,4â²-bipy)(H2O)2]·2.24H2O}n(5), {[Cu(6-sinic)(4,4â²-bipy)0.5]·CH3OH·H2O}n(6), [Cd2(6-mna)2(phen)]n(7), and {[Cd(cpds)(bpe)]·2.2H2O}n(8) were prepared by self-assembly of disulfide derivative of the nicotinate, 6,6â²-dithiodinicotinic acid (H2cpds) with transition metal ions in the absence of different N-donor ligands (4,4â²-bipy = 4,4â²-bipyridine, 2,2â²-bipy= 2,2â²-bipyridine, phen = 1,10-phenanthroline, bpe = 1,2-bis(4-pyridyl)ethene, 6-sinic = 6-sulfinto-nicotinate, 6-mna = 6-mercaptonicotinic acid). X-Ray structure analyses of 1â8reveal their structure ranging from the discrete unit (0D) (4), one-dimensional (1D) (1, 5), two-dimensional (2D) (7), non-interpenetrating 3D porous coordination polymers (6, 8), 2-fold interpenetrated structure (2) to a 5-fold interpenetrating framework (3), which mainly due to the differences in the bridging modes of cpds2âand the effect of the secondary ligands. Interestingly, in the complexes 6and 7, the starting H2cpds reagent is converted into new ligands (6-sinic in 6and 6-mna in 7) under solvothermal condition viain situcleavage of SâS bond. In addition, thermogravimetric analyses, X-ray powder diffractions and the fluorescent properties of complexes 1, 2, 3, 7, 8have been investigated. [ABSTRACT FROM AUTHOR]
