[N,N′-Bis(4-chlorobenzylidene)-2,2-dimethylpropane-1,3-diamine-κ2 N,N′]iodidocopper(I)
The mol-ecule of the title compound, [CuI(C(19)H(20)Cl(2)N(2))], lies across a crystallographic mirror plane. The coordination around the copper centre is distorted trigonal planar, with a bite angle of 94.40 (7)°. A six-membered chelate ring is formed by the coordination of iminic N atoms of the bidentate ligand to the Cu(I) atom, adopting a chair conformation. This conformation is required if...
متن کاملویراستار سنتز و ساختار بلوری ترکیبات باز شیف N-(3,4-dimethoxybenzylidene)-4-methoxyaniline (1) و N-(3,4-dimethoxybenzylidene)-4-ethoxyaniline (2)
New Schiff-base compounds N-(3,4-dimethoxybenzylidene)-4-methoxyaniline (1) and N-(3,4-dimethoxybenzylidene)-4-ethoxyaniline (2) were synthesized and characterized by elemental analyses (CHN) and FT-IR spectroscopic techniques. Crystal structures of 1 and 2 were obtained by single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic, space group P21 with two independent molecule...
متن کامل4-Ethoxy-N-(4-ethoxyphenyl)-N-(4-nitrophenyl)aniline
In the title mol-ecule, C22H22N2O4, the eth-oxy-phenyl rings are oriented at dihedral angles of 69.31 (13) and 75.90 (13)° to the nitro-phenyl ring and are twisted to each other, making a dihedral angle of 78.55 (13)°. In the crystal, weak C-H⋯O hydrogen bonds and C-H⋯π inter-action link the mol-ecules into a three-dimensional supra-molecular architecture.
متن کاملN 4,N 4′-Bis(4-methoxybenzylidene)-3,3′-dimethylbenzidine
The mol-ecule of the title compund, C(30)H(28)N(2)O(2), a Schiff base synthesised via a condensation reaction between 4-meth-oxy-benzaldehyde and 3,3'-dimethyl-benzidine, a crystallographic twofold rotation axis passes through the mid-point of the C-C bond of the biphenyl unit. Thus, the asymmetric unit comprises one half-mol-ecule. In the biphenyl unit, the aromatic rings are twisted by 13.49 ...
متن کامل4-(4-Nitrostyryl)-N,N-diphenylaniline
In the triaryl-amine group of the title compound, C(26)H(20)N(2)O(2), the N atom adopts an approximately trigonal-planar geometry, lying 0.046 (5) Å from the plane P defined by its three neighbouring C atoms; the benzene and two terminal phenyl rings are twisted by 37.4 (1), 31.4 (1) and 47.8 (1)°, respectively from plane P. In the trans-stilbene fragment, the two benzene rings form a dihedral ...
