this work, the synthesis and characterization of new silver(I) complexes, that include N′-[(E)-(pyridine-2-ylmethylene)pyrazine-2-carbohydrazide, HPCPH, as main ligand and substituted aryl-phosphines as auxiliary ligands, is reported. HPCPH was synthesized from pyrazinoic acid, the active metabolite of the first-line antimycobacterial drug pyrazinamide. Complexes [Ag(HPCPH)(PPh3)2]OTf (1), [Ag(HPCPH)((P(p-tolyl)3)2]OTf
尽管是一种可预防和可治愈的疾病,结核病 (TB) 仍是世界头号传染病杀手。迫切需要开发新药。在这项工作中,合成和表征了新的银 (I) 配合物,包括N '-[( E )-(pyridine-2-ylmethylene)pyrazine-2-carbohydrazide,HPCPH,作为主要配体和取代的芳基膦作为辅助配体,据报道。HPCPH 由吡嗪酸合成,吡嗪酸是一线抗分枝杆菌药物吡嗪酰胺的活性代谢物。配合物 [Ag(HPCPH)(PPh 3 ) 2 ]OTf (1) , [Ag(HPCPH)((P( p -tolyl ) 3 ) 2 ]OTf (2)和 [Ag(HPCPH)(P( p-anisyl) 3 ) 2 ]OTf (3)通过元素分析和 FTIR 和 NMR 光谱(OTf三氟甲磺酸盐)在固态和溶液中进行了表征。(1,2)的晶体结构由XRD确定。Ag 原子与 HPCPH 配体的偶氮甲碱和
