Trans-[Co(NH3)4(NH2CH3)(CH3)2 SO]3+ and trans-[Co(NH3)4(NH2CH3)(CH3) NCHO]3+ ions are prepared by Ag+-induced solvolysis of trans-[Co(NH3)4(NH2 CH3)X]2+ (X = Cl or Br) complexes in dimethylsulphoxide or dimethylformamide. The complexes were characterized by electronic, IR ...
化合物碱性强弱:NH3 >CH3NH2 >H2CO3;[1.因为同基的无机碱性大于有机的;2.H2CO3属于酸].
The present article is devoted to the characterization of the structural phase transitions of the [CH3NH3][Co(COOH)3] (1) perovskite-like metal–organic compound through variable-temperature single-crystal neutron diffraction. At room temperature, compound 1 crystallizes in the orthorhombic space group...
