Co-ligand tuned pyrimidine-2-carboxylate Mn(II) complexes from a 2D 63 layer to an interpenetrated srs-net was written by Sun, Rui;Gao, Su-Mei;Wang, Shao-Qiang;Song, Wei-Chao;Zhao, Jiong-Peng;Liu, Fu-Chen. And the article was included in Dalton Transactions in 2017.COA of Formula: C4H3N3O4 This article mentions the following:
A 63 2D layer complex [Mn3Cl3(L3)]n·H2O (1) (L = pyrimidine-2-carboxylate) was obtained by assembling 2-cyanopyrimidine and manganese chloride, in which the L ligands were generated in situ. In 1 six-membered Mn rings were constructed from MnII ions and L ligands, which were connected to each other by double chloride anions affording a 2D layer. When the chloride anions in 1 were substituted partly by formate, [Mn4Cl3L4(HCO2)]n (2) was obtained. In 2, the L ligands bridge MnII to give a 1D chain, which was further connected by the double chloride anions and Cl/formate bridges to form a two-fold interpenetrated srs-net. 2 Exhibits an obvious SHG response of ∼0.8 times that of KDP. Furthermore, 2 is an antiferromagnet with a field induced spin flop transition. In the experiment, the researchers used many compounds, for example, 1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6COA of Formula: C4H3N3O4).
1H-1,2,3-Triazole-4,5-dicarboxylic acid (cas: 4546-95-6) belongs to triazole derivatives. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to azides. Both the triazoles and their derivatives have significant biological properties including antimicrobial, antiviral, antitubercular, anticancer, anticonvulsant, analgesic, antioxidant, anti-inflammatory, and antidepressant activities.COA of Formula: C4H3N3O4
