Cheng, Yuan-Zheng published the artcileSynthesis and crystal structure of Pb(II) complex with 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone, Recommanded Product: 4-Benzoyl-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, the publication is Main Group Metal Chemistry (2014), 37(3-4), 101-106, database is CAplus.
A new Pb(II) complex, Pb(PMBP)2 (PMBP = 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone), was synthesized and characterized by IR spectroscopy and x-ray single-crystal diffraction. X-ray crystallog. data showed that the complex crystallizes in the monoclinic space group C2 with a 22.060(7), b 6.981(2), c 9.127(3) Å, β = 90.768(7), C34H26N4O4Pb, Mr = 761.79, D = 1.800 g/cm3, μ(MoKa) = 6.050, F(000) = 744, Z = 2, final GooF = 1.067, R = 0.0195, and Rw = 0.0468 for 1353 observed reflections [I>2σ(I)]. The compound exhibits monomeric species that were linked by a C-H···π interaction, intermol. C-H···O H bonds, and intermol. longer secondary Pb···X (X = C or N) interactions; therefore, two-dimensional layered networks were obtained.
Main Group Metal Chemistry 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.
