Keywords: coordination polymer lead aminonicotinate hydroxynicotinate complex preparation crystal structure; Knoevenagel condensation catalyst coordination polymer lead aminonicotinate complex; luminescence sensor coordination polymer lead hydroxynicotinate complex; thermal stability coordination polymer lead aminonicotinate hydroxynicotinate complex.They researched the compound: 5-Hydroxynicotinic acid( cas:27828-71-3 ).Electric Literature of C6H5NO3. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:27828-71-3) here.
Two new PbII-based coordination polymers based on 5-aminonicotinic acid (namely HL-NH2) and 5-hydroxynicotinic acid (namely HL-OH) are both successfully synthesized under solvothermal synthesis conditions. PbCl2 and HL-NH2 can generate a 3D network with the formula of {[Pb3(L-NH2)2Cl5]·(H2O)}n (complex 1). The -NH2 functional group is replaced by -OH on the organic linker to further coordinate with PbII to fabricate another 3D framework of [Pb2(L-O)Cl2]n (complex 2). Various and fanatics structures can be tuned and regulated by different functional substituent groups. Furthermore, complex 1 can be applied as a high-efficient heterogeneous catalysis for Knoevenagel condensation reaction. Meanwhile, complex 2 is an excellent potential luminescent sensor for Fe3+.
