dichloro-tetrakis-(2‑hydroxy-5-methylphenyl)(1H-pyrazol-4-yl)-methanonezinc(II) complex, [Zn(HMPM)4Cl2], has been synthesized and characterized by spectral, structural and biological studies. Its crystal structure was solved by single crystal X-ray diffractometry. The ligand, (2‑hydroxy-5-methylphenyl)(1H-pyrazol-4-yl)methanone, (HMPM), has been prepared by condensation of 3-formyl-6-methyl chromone with thiosemicarbazide
一种新的四叶螺旋桨轴类锌络合物,二氯-四-(2-羟基-5-甲基苯基)(1H-吡唑-4-基)-甲酮锌(II)络合物,[Zn(HMPM) 4 Cl 2 ]已通过光谱、结构和生物学研究进行合成和表征。通过单晶X射线衍射分析其晶体结构。配体 (2-羟基-5-甲基苯基)(1H-吡唑-4-基)甲酮 ( HMPM ) 由 3-甲酰基-6-甲基色酮与氨基硫脲缩合制备。[ Zn(HMPM) 4 Cl 2 ]配合物以中心对称单斜晶系P 2 1 / n结晶具有晶胞尺寸的空间群,a =13.2068 Å, b =7.0763 Å, c =23.5910 Å, β = 102.327° 从 XRD 数据可以得出[Zn(HMPM) 4 Cl 2 ]是一种略微扭曲的八面体配合物,具有4个HMPM通过它们的吡唑的sp 2氮和占据反式位置的2个氯化物作为单齿配体。晶体中的每个[Zn(HMPM) 4 Cl 2 ]分子均呈现ac
