C₃ symmetric vanadium(iii) complexes with O,N-chelating hexadentate tripodal ligands of pyrazolone

Abstract

Novel C3 symmetric vanadium(iii) complexes of tripodal ligands of pyrazolones were synthesized and characterized by various spectroscopic and analytical techniques including single crystal XRD.

Binary and Ternary Zinc(II) Complexes of Acyl Pyrazolones: Synthesis, Spectroscopic Analysis, Crystal Structure and Antimalarial Activity

“…Acyl pyrazolones are widely used in coordination chemistry due to the nature of the bidentate ligand . A wide range of applications has been studied in the field of biological activity of metal complexes of acyl pyrazolone . The d 10 metal complexes of the acyl pyrazolones and their structural analogues showed decent fluorescence properties, antimicrobial and antitumor activity .…”

Substituent Controlled Synthesis of Dioxidomolybdenum(VI) Complexes of N,N,N’,N’‐Tetrakis(2‐Hydroxyl‐3,5‐Disubstitutedbenzyl)‐1,2‐Diaminoethane, Their Trans‐Metalation to Oxidovanadium(V) Complexes and Biocatalytic Applications

“…Complexes 7 , 8 , 9 , 11 and 12 are mononuclear with one terminal oxide atom, O(1), in each one and the vanadium coordination environment is completed by five heteroatoms ONNOO of the ligands. The three complexes ( 7 , 8 and 9 ) contain a racemic mixture of enantiomers (Figures S32 and S33) [59] . Compounds 7 , 8 , 11 and 12 contain only one isomer in the asymmetric unit and compound 9 contains two enantiomers in the asymmetric unit (Figure S34).…”
