Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5-Hydroxynicotinic acid, is researched, Molecular C6H5NO3, CAS is 27828-71-3, about Self-assembly syntheses and crystal structures of triorganotin(IV) pyridinecarboxylate: 1D polymers and a 42-membered macrocycle.SDS of cas: 27828-71-3.
A series of new triorganotin(IV) pyridinecarboxylates with 6-hydroxynicotinic acid (6-OH-3-nicH), 5-hydroxynicotinic acid (5-OH-3-nicH) and 2-hydroxyisonicotinic acid (2-OH-4-isonicH) of the types: [R3Sn (6-OH-3-nic)·L]n (I) (R = Ph, L = Ph·EtOH, 1; R = Bn, L = H2O·EtOH, 2; R = Me, L = 0, 3; R = n-Bu, L = 0, 4), [R3Sn (5-OH-3-nic)]n (II) (R = Ph, 5; R = Bn, 6; R = Me, 7; R = n-Bu, 8), [R3Sn (2-OH-4-isonic·L)]n (III) (R = Bn, 9, L = MeOH; R = Me, L = 0, 10; R = Ph, 11, L = 0.5EtOH) have been synthesized. All the complexes were characterized by elemental anal., TGA, IR and NMR (1H, 13C, 119Sn) spectroscopy analyses. Among them, except for complexes 5 and 6, all complexes were also characterized by x-ray crystallog. diffraction anal. Crystal structures show that complexes 1-10 adopt 1D infinite chain structures which are generated by the bidentate O, O or N, O and the five-coordinated tin centers. Significant O-H···O, and N-H···O intermol. hydrogen bonds stabilize these structures. Complex 11 is a 42-membered macrocycle containing six tin atoms, and forms a 2D network by intermol. N-H···O hydrogen.
《Self-assembly syntheses and crystal structures of triorganotin(IV) pyridinecarboxylate: 1D polymers and a 42-membered macrocycle》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(5-Hydroxynicotinic acid)SDS of cas: 27828-71-3.
