Marchetti, Fabio published the artcileSynthesis and characterization of copper(I) and copper(II) coordination compounds containing 4-acylpyrazolon-5-ato ligands.

New [(Q)2CuII] and [(Q)2(L)CuII] derivatives (in general QH is 1-R-3-methyl-4-R’-pyrazol-5-one; in particular: Q’H: R = C6H5, R’ = C6H5(C=O); Q”H: R = C6H5, R’ = CH3(C=O); QFH: R = C6H5, R’ = CF3(C=O); QClH: R = C6H5, R’ = CCl3(C=O); QBrH: R = C6H5, R’ = p-BrC6H4(C=O); QAH: R = C6H5, R’ = p-CH3O-C6H4(C=O), QEH: R = C6H5, R’ = C6H13(C=O); QMH: R = CH3, R’ = C6H5(C=O); QDH: R = CH3, R = CH3(C=O); QBH: R = C6H5, R’ = C6H5(C=N(p-CH3C6H4)); L = 2,2′-bipyridine or 1,10-phenanthroline) were synthesized and characterized through anal. and spectral techniques. When (Q)2CuII interacted with an excess of PPh3, reduction to Cu(I) was observed and (Q)Cu1(PPh3)2 complexes were synthesized. (QF)CuI(PPh3)2 was characterized by single crystal x-ray diffraction in monoclinic space group P21\/c, R = 0.069. The coordination environment of Cu is a distorted tetrahedron: the P-Cu-P angle is 127.8(1)\u00b0 and the ligand bite O-Cu-O angle is 87.8(3)\u00b0; the Cu-O bond distances are 2.075(7) and 2.109(7) \u00c5, while Cu-P are 2.246(3) and 2.254(3) \u00c5.<\/p>\n

Polyhedron published new progress about Crystal structure. 1691-93-6 belongs to class pyrazoles-derivatives, name is 5-Methyl-2-phenyl-4-(2,2,2-trifluoroacetyl)-1H-pyrazol-3(2H)-one, and the molecular formula is C12H9F3N2O2, SDS of cas: 1691-93-6<\/a>.<\/p>\n
