X-ray crystal structures of two coordination isomers of Ru(CO)2Cl2(APT)》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine)Safety of 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine.

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: 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine, is researched, Molecular C12H10N6, CAS is 1671-88-1, about Ruthenium carbonyl complexes of N-heterocyclic molecules. Part 3. Synthesis of ruthenium complexes of the ambidentate ligand 4-amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole (APT). X-ray crystal structures of two coordination isomers of Ru(CO)2Cl2(APT).Safety of 3,5-Di(pyridin-2-yl)-4H-1,2,4-triazol-4-amine.

4-Amino-3,5-bis(pyridin-2-yl)-1,2,4-triazole (APT), a poly- and ambidentate ligand, forms 2 bidentate coordination isomers of Ru(CO)2Cl2, which in 1 case is coordinated to a pyridyl ring and an adjacent triazole ring (A), and in the other case to a pyridyl ring and the amino N atom (B). Both isomers of Ru(CO)2Cl2(APT) were crystallog. characterized: A, orange, orthorhombic, space group Pbca, a 15.332(4), b 17.715(4), c 13.083(4) Å, R = 3.26%; B(MeOH), yellow, triclinic, space group P1̅, a 8.712(2), b 9.492(2), c 12.142(2) Å, α 86.03(2), β 82.63(2), γ 74.21(2)°, R = 3.49%. The complexes are formed directly from the reaction of [Ru(CO)2Cl2]n with APT in boiling MeOH. In a similar reaction with Re(CO)5Cl, Re(CO)3Cl(APT) is formed. The Br analog of the Ru complex forms predominantly the yellow isomer (B), while the I analog crystallizes only as the orange isomer (A). Based on NMR data, the Re complex most likely coordinates via the A mode.
