Synthesis, 1H-NMR, GC-MS Characterization, and in Vitro Bactericidal Studies of an Aqueous Soluble Vanadium (IV) Complex with Dipicolinic Acid and Methylsalysilateligands

Material and MethodsAll microbiological standards and vanadium medium were prepared in ultra-pure water (UPW) and purified through a Barnstead/Thermolyne (Dubuque, IA) with a water resistance from 0.01 to 18.3 mega-ohm-cm (18-M).The elemental analysis was checkedon an Agilent 7890GC system coupled to an Agilent 7000GC/MS Triple Quad spectrometer with an Elite-I fused silica capillary column (30mx0.25mmIDx0.25µm (HP-5ms).The proton NMR spectrum was collected on a Bruker Avance III 400MHz NMR spectrometer; FTIR spectra were collected as KBr disk on a Nicolet iS50 FTIR spectrometer.The strain microorganisms
