Reaction between the NH4VO3 and pyridoxal semicarbazone (PLSC) in a methanol/ammonia solution forms an orange, diamagnetic, mononuclear NH4[VO2(PLSC-2H)] complex in which vanadium is in the oxidation state +5, and pyridoxal semicarbazone is coordinated in its dianionic form. The complex cocrystallizes with a neutral molecule of PLSC and two water molecules. The coordination environment around vanadium can be described as an almost ideal square-pyramid. The complex was characterized by elemental analysis, conductometric and magnetochemical measurements, IR spectra, X-ray diffraction, and in vitro cytotoxicity analysis.
在甲醇/氨溶液中，偏钒酸铵（NH₄VO₃）与吡哆醛缩氨基脲（PLSC）反应形成一种橙色、抗磁性的单核NH₄[VO₂(PLSC - 2H)]配合物，其中钒的氧化态为 +5，吡哆醛缩氨基脲以其二价阴离子形式配位。该配合物与一个PLSC中性分子和两个水分子共结晶。钒周围的配位环境可描述为一个几乎理想的正方锥。通过元素分析、电导和磁化学测量、红外光谱、X射线衍射以及体外细胞毒性分析对该配合物进行了表征。
