Synthesis, crystal structure, and spectra of the trichloromethane solvate of nickel(II) 9(E)-phenanthrene-9,10-dione[(1Z)-3,3-dimethyl-3,4- dihydroisoquinolin-1(2H)-ylidene]hydrazonate

The complex [Ni(L-H)2] • CHCl3 (I), where L-H is the (9E)-phenanthrene-9,10-dione[(1Z)-3,3-dimethyl-3,4-dihydroisoquinolin-1(2H) -ylidene]hydrazone anion (L), was synthesized for the first time. The crystal structure of I was solved. The L-H and L-H′ anions exist as cis- and trans-isomers and are linked to the central Ni2+ atom in a tridentate chelating mode giving rise to two conjugated five-membered metal rings of different composition (NiN3C and NiONC2) at each anion. The Ni2+ coordination polyhedron is a highly distorted octahedron whose axial positions are occupied by N(3) and N(3)′ atoms. The vertices of the tetrahedrally distorted equatorial base of the octahedron are occupied by the N(1) and N(1)′ atoms of the dihydroisoquinoline fragment (A) and the O(1) and O(1)′ atoms of the phenanthrenequinone fragment (B). Complex I occurs as the cis-isomer. The conformations of the L-H anions in I and the L molecules in L • H2O do not differ much. The randomly disordered CHCl3 solvent molecules in I occupy crystal voids between the centrosymmetric dimeric associates. Spectroscopic (IR and UV-Vis) characteristics of I were obtained. © 2011 Pleiades Publishing, Ltd

Synthesis, crystal structure, and electronic structure of a copper(II) chloride complex with 9(E)-phenanthrene-9,10-dione[(1Z)-3,3-dimethyl-3,4- dihydroisoquinolin-1(2H)-ylidene]hydrazone [Cu2(L-H) 2Cl2]

The [Cu2(L-H)2Cl2] compound (I) has been obtained by the reaction of 9(E)-phenanthrene-9,10-dione[(1Z)-3,3-dimethyl-3,4- dihydroisoquinolin-1(2H)-ylidene]hydrazone with copper(II) chloride. The crystal and molecular structure of I has been determined by X-ray crystallography. The L-H anion acts as a tridentate chelating ligand and is coordinated to the Cu atom through the O(1) atoms of the phenanthrenequinone moiety, the N(1) atom of the dihydroisoquinoline moiety, and the N(3) atom of the azo group to form two five-membered chelate rings. Complex I is a dimer with a double chloride bridge. The coordination polyhedron of the Cu atom is completed to a distorted pyramid by two chlorine atoms. The molecular and electronic structures of the L molecule and the model [Cu(L-H)Cl] complex have been determined by the density functional theory method.

Synthesis, crystal structure, and spectra of 9(E)-phenanthrene-9,10- dione[(1Z)-3,3-dimethyl-3,4-dihydroisoquinolin-1(2H)-ylidene]hydrazone and its cation-anion complex with copper(I) bromide

The reaction of 1-hydrazino-3,3-dimethyl-3,4-dihydroisoquinoline with 9,10-phenanthrenequinone gave (9E)-phenanthrene-9,10-dione[(1Z)-3,3-dimethyl-3, 4-dihydroisoquinolin-1(2H)-ylidene]hydrazone (L). The reaction of L with copper(II) bromide gave the complex (LH)[CuBr2]. The crystal structures of the monohydrate L • H2O (I) and the isolated complex (LH)[CuBr2] (II) were determined by X-ray diffraction. The structural units of I are pseudo-centrosymmetric dimers in which the L and water molecules are combined by strong hydrogen bonds. The active H atom is located at the N(1) atom of the isoquinoline fragment of the L molecule. The L molecule occurs in the crystal as the cis, trans isomer with respect to exocyclic C=N bonds at the isoquinoline and phenanthrenequinone fragments, respectively. Complex II has a cation-anion structure. The LH+ cation as the cis, cis isomer is protonated at N(2) and stabilized by two intramolecular hydrogen bonds. In the CuBr 2 - anion, the copper atom in the oxidation state +1 has a linear coordination, the C-Br bond length is 2.185(4) ± 0.005 Å, and the BrCuBr angle is 179.8(4)°. The main ion-ion interactions in structure II are shortened contacts involving bromine atoms, which combine cations and anions into a three-dimensional framework. © 2009 Pleiades Publishing, Ltd

(9E)-Phenanthrene-9,10-dione[(1Z)-3,3-dimethyl-3,4-dihydroisoquinolin-1(2H) -ylidene]hydrazonium bromide (LH)Br (I) was synthesized. The models of protonated forms of the LH+ cation were calculated by quantum-chemical methods, and their relative stability was estimated. The crystal structure of compound I was determined by X-ray diffraction analysis. Compound I is built according to the cation-anion type (the mobile protons are located at the nitrogen atoms). The cation exists in the s-cis,cis-isomeric form stabilized by two cyclic hydrogen bonds. The π-electron density is localized on the multiple bonds N(1)-C(1) (1.292(4) Å) and N(3)-C(12) (1.294(4) Å). The spectroscopic characteristics (IR and electronic absorption spectra) of compound I are obtained. © Pleiades Publishing, Ltd., 2010
