Abstract: Abstract Four novel coordination polymers, namely, [Co(L1)Cl(H2O)]n (1), [Mn(L1)Cl(H2O)]n·nH2O (2), [Co3(L2)2(H2O)2]n·nCH3CN·nH2O (3), [Mn3(L2)2(H2O)12]n·1.5nH2O (4) were solvothermally constructed by two N-heterocyclic carboxylate bifunctional ligands, 1-(4-carboxylphenyl)-3-(prazin-2-yl)-1H-1,2,4-triazole (HL1) and 5-(2,3-dicarboxylphenoxy)nicotic acid (H3L2). Compounds 1, 2 and 4 exhibit… read more here.

Abstract: Abstract Three new inorganic-organic hybrids constructed from a half rigid N-heterocyclic carboxylate ligand, K[Ag3(HL1)4](Mo8O26) (1), [Ag4(HL1)2(HL2)2(SiMo12O40)] (2) and (H3O)[Ag(L1)2]·2H2O (3) [HL1 = 1-(4-carboxylbenzyl)-3-(pyrazine-2-yl)pyrazole; HL2 = 3-(2-pyrazine)pyrazole], were hydrothermally synthesized and characterized. In compound 1, {K[β-Mo8O26]}n3n− chains fill in the… read more here.
