 Title    The Metal Chelates of Heterocyclic /3-Diketones and their Derivatives, Part IV New Mixed Ligand Tetrakis Complexes of Lanthanides Derived from tris-Acetylacetonates and Some 4-Acyl Pyrazolones  
 Abstract    Some new mixed ligand tetrakis chelates derived from tris acetylacetonates of La, Ce, Pr, Nd, and Gd -with other /?-diketones, like l-phenyl-3-methyl-4-benzoyl-pyrazolone-5 and l-phenyl-3-methyl-4-acetyl-pyrazolone-5 have been synthesised. The compounds are characterised by elemental analyses and IR data. The UV spectral properties and the conductance in DMF have also been reported.

 Title    Compounds of Complex Halo and Pseudohalo Acids of the Group II B Metals, Part HI [1] Spectral Studies of the Hglä Ion  
 Abstract    A study has been made of the Far-IR spectra (250-30 cm -1) of the complexes HHgl3 • 2 Py and HHgl3 • 2 An (Py = pyridine and An = aniline), in the solid state. Associated anionic structures are present in the two complexes. The UV spectrum of the aniline complex, in three solvents, shows that the Hgl3~ ion is the predominant anionic species in solution.
