Li, He published the artcileStructural diversity and properties of four complexes with 4-acyl pyrazolone derivative, Recommanded Product: 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, the publication is Polyhedron (2013), 209-215, database is CAplus.
Four {[Zn(HL)(H2O)(DMF)](NO3)}n (1), [Cd(HL)2]n (2), {[Mn(HL)2]·MeCN·2H2O} (3) and {[Mn(L)(μ2-EtOH)]}n (4) (H2L = N-(1-phenyl-3-methyl-4-benzal-pyrazolone-5)-nicotinic hydrazide) were synthesized and characterized by elemental analyses, IR spectra, thermal analyses and single crystal x-ray diffraction. The structural analyses reveal that complexes 1, 2 and 3, formed by H2L with metal nitrate, have Zigzag chain, double-stranded chain and mononuclear structures, resp., and the ligands adopt three different coordination modes in these complexes. While, complex 4, formed by H2L with Mn acetate, represents a 2-dimensional network structure with dinuclear units bridged by EtOH mols. The metal atom and counteranion have certain influences on the structures of resulting complexes. The fluorescent properties of 1 and 2 and the magnetism of 4 were studied.
Polyhedron published new progress about 4551-69-3. 4551-69-3 belongs to pyrazoles-derivatives, auxiliary class Benzenes, name is 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, and the molecular formula is C17H14N2O2, Recommanded Product: 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one.
