The complex [Fe(Phen)3][iso-Bu2PS2)2 (I) was synthesized and the single crystals of [Fe(Phen)3](iso-Bu2PS2)2 · 5H2O (II) were grown. The disulfan {iso-Bu2P(S)S}2 (III) was isolated. Compound II consists of the complex cations [Fe(Phen)3]2+, the outer-sphere anions iso-Bu2PS 2 ? , and the molecules of water of crystallization. The coordination polyhedron of the Fe atom is a distorted N6 octahedron. Complex I is diamagnetic, and thus, the full spin of the Fe2+ ion S = 0. The structure of III is built of the molecules containing the S-S bridge 2.061(1) Å in length. 相似文献

Mixed-ligand complex compounds [Pb(Phen)(i-Bu2PS2)]2 (I) and [Pb(2,2′-Bipy)(i-Bu2PS2)]2 (II) were synthesized. Their structures were determined from X-ray diffraction data (X8 APEX diffractometer, MoK

. Crystals II are monoclinic: a = 9.3462(3) Å, b = 26.3310(12) Å, c = 28.5345(13) Å; β = 96.436(1)°, V = 6977.9(5) Å3, Z = 8, ρcalc = 1.489 g/cm3, space group P21/n. The structures are built from mononuclear molecules. In both structures, the intermolecular contacts between the Pb and
S atoms of the neighboring mononuclear molecules form supramolecular assemblies involving two molecules. The environment of
the Pb atoms in the assemblies is a pentagonal bipyramid, N2S4+1. The assemblies are joined into ribbons by π-π interactions of the Phen rings in I and C…C short contacts between the pyridine rings in II.

Coordination compounds [CoLCl2] (I), [CuLCl(NO3)] (II), CuL(NO3)2 (III), and CuLCl2 (IV) (where L is a chiral pyrazolylquinoline—a derivative of terpenoid (+)-3-carene) were synthesized. X-ray diffraction data showed that crystal structures I and II are built of mononuclear acentric molecules. In the molecule of complex I, the Co2+ ion coordinates two N atoms of bidentate cycle-forming ligand L and two Cl atoms. The coordination polyhedron of Cl2N2 is a distorted tetrahedron. For complex I, μeff = 4.50 μB, which corresponds to a high-spin configuration d 7. In the molecules of II(1), II(2) (which are diastereoisomers of complex II), each Cu2+ ion coordinates two N atoms of bidentate cycle-forming ligand L, the Cl atom, and two O atoms of bidentate cyclic NO 3 ? ion. The ClN2O2 coordination polyhedra are tetragonal pyramids with different degrees of distortion. The structure of complex II consists of supramolecular clusters, i.e., isolated chains incorporating the molecules of II(1) and II(2). The values of μeff for II–IV correspond to the d 9 configuration. The results of EPR and IR study suggest that complex III contains the O4N2 polyhedron, whereas complex IV contains the Cl2N2 polyhedron. Complexes I and IV were found to show a high catalytic activity in ethylene polymerization reaction. 相似文献

Linear systems of ordinary differential equations with periodic coefficients are considered and some numerical algorithm is proposed for analyzing the asymptotic stability of the zero solution that is based on the Runge-Kutta method of the fourth order of accuracy. 相似文献

The crystal and molecular structure of the mixed-ligand complex Zn(S2CN(i-C4H9)2)2Phen was determined by single-crystal X-ray diffractometry (Syntex P21 diffractometer, CuKα radiation, 1738 F(hkl),R = 0.036). The crystals are triclinic, a =18.564(4), b =10.487(1), c =17.505(4) å, α = 84.04(2), Β =94.88(2), γ =90.87(2)?;V =3377(1) å 3, Z = 4, dcalc = 1.287 g/cm3, space group C-1. The structure consists of monomeric molecules in which the zinc atom has a distorted octahedral environment (4S+2N). 相似文献
