Complex [Cu(HL1)2]Cl2 ⋅ 1.34 Н2О (HL1 = p-(t-Bu)C6H4CONHN(Me)2) is studied by X-ray diffraction analysis. The coordination polyhedron of the copper atom is a distorted tetragonal pyramid, whose base is formed by the amine N and O atoms of two ligands HL1, and one of the chlorine atoms occupies the vertex. The second chlorine atom does not enter into the coordination sphere of copper but is linked through

Direct N,N-dialkylation of acylhydrazide catalyzed by a series of amidato iridium complexes bearing an electron-donating group in the ligand using methanol or ethanol as the alkyl reagent under weak base conditions (10 mol % KHCO3) is described. A wide range of acylhydrazidederivatives are converted to the corresponding N,N-dialkylated products in excellent yields (38 examples, yields of ≤96%).

The extraction of copper(II) with the para-tert-butylbenzoic acid hydrazide and related N',N'-dimethyl derivative was studied. The composition and structure of the extracted complexes were determined, the mechanism of extraction of copper(II) in different media was suggested, the extraction constant was calculated. The copper(II) complex compounds with these reagents were isolated.

The X-ray diffraction analysis of [Cu(p-(t-Bu)C6H4CONHN(Me)(2))]Cl-2 (I) has been performed. The complex is binuclear. Its structure represents a centrosymmetric dimer. Copper atoms are linked to each other via two bridging chlorine atoms. The copper coordination polyhedron is a distorted trigonal bipyramid. The dialkylhydrazide reagent is a bidentate (O, N(2)) ligand linked to the central atom to form a five-membered chelate ring, which has an envelope conformation with a copper atom in its "flap." Crystals are monoclinic.

X-Ray diffraction analysis was performed for the copper(II) chelate with para-(tert-butyl)benzoic acid N',N'-dimethylhydrazide, Cu(p-(tert-Bu)C6H4CONHNMe2)(2) (I). The reagent functions as a bidentate (O,N(2)) ligand giving a five-membered copper-containing ring. The molecule is centrosymmetric. The Cu atom and the metal rings lie in the same plane. The coordination polyhedron of copper is a slightly distorted square. The crystals are monoclinic: a = 16.2634(14) , b = 9.0415(8) , c = 9.6415(9) , alpha = 90A degrees, beta = 100.052(7)A degrees, Z = 2, space group P2(1)/c.
