The scandium complexes of Sc(PMBP) 3 $H 2 O (non-crystal) and Sc(PMBP) 3 (crystal) with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP) were prepared and characterized by thermal analysis, IR, NMR and MS spectroscopies. The crystal structure of the complex, obtained by X-ray analysis, indicates that
Molecular structures of the two tautomers of a -diketone 1-phenyl-3-methyl-4-benzoyl-5pyrazolone (PMBP) were studied by MS, UV, IR, and X-ray diffraction methods. The mass spectra show little difference for the two forms of PMBP, while there are notable differences in the IR spectra as KBr pellets
## Abstract 1,2,4‐Triphenyl‐1,3,5‐triazapentadiene (1a), prepared from benzamidine and __N__‐phenylbenzimidoyl chloride, was treated at room temperature with CoCl~2~, Ni(NO~3~)~2~, Na~2~PdCl~4~, CuCl~2~ and ZnCl~2~ to form the corresponding six‐membered 1:1 chelate complexes 1a·CoCl~2~, 1a·Ni(NO~3~
