Two new binuclear complexes, [Mn2(μ-dmpo)2(SCN)4(H2O)2] (1, dmpo = 3,5-dimethylpyridine N-oxide), [Mn2(μ-po)2(H2O)6I2]I2 (2, po = pyridine N-oxide), were synthesized and their crystal structures determined by x-ray crystallog. Complexes 1 and 2 crystallize in monoclinic, space group P21/c, with a 8.8836(18), b 15.450(3), c 15.484(3) Å, β 91.020(3)° for 1, and a 8.8352(13), b 17.927(3), c 8.3338(12) Å, β 103.765(2)° for 2. In each binuclear complex two Mn(II) were bridged by two 3,5-dimethylpyridine N-oxides or by two pyridine N-oxides and the distances between the bridged Mn(II) ions are 3.599 Å for 1 and 3.552 Å for 2. Variable temperature (4-300 K) magnetic measurements were performed for 1 and the susceptibility data were fitted by using a binuclear Mn(II) magnetic coupling formula producing the 2J = -2.17 cm-1. In the experiment, the researchers used many compounds, for example, 3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8Related Products of 3718-65-8).
3,5-Dimethylpyridine 1-oxide (cas: 3718-65-8) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Related Products of 3718-65-8
