We report on the synthesis, crystal structure, magnetic, thermodn., and electron-spin-resonance properties of the coordination complex [Cu2(pz)3(4-HOpy)4](ClO4)4 (pz=pyrazine; 4-HOpy=4-hydroxypyridine). This material is identified as a spin-1/2 Heisenberg ladder system with exchange-coupling parameters Jrung/kB = 12.1(1)K and Jleg/kB = 10.5(3)K[Jrung/Jleg = 1.15(4)]. For single crystals our measurements revealed two critical fields, Μ0Hc1=4.63(5)T and Μ0Hc2=22.78(5)T (for H||a*), separating the gapped spin-liquid, gapless Tomonaga-Luttinger-liquid, and fully spin-polarized phase. No signature of a field-induced transition into a magnetically ordered phase was found at temperatures down to 450 mK. The material bridges an important gap by providing an excellent phys. realization of an almost isotropic spin-1/2 strong-rung Heisenberg ladder system with modest exchange-coupling energy and critical-field scales. In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2HPLC of Formula: 626-64-2).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. HPLC of Formula: 626-64-2
