A series of cis-{RuCl2(PPh3)2[4,4-(X)2-2,2-bipy]} [cis-chlorines; X=-H, -Me, -SMe, and (-Cl,-Me)] complexes have had their structures determined by single crystal X-ray diffraction. The geometry of these complexes, also determined in CH2Cl2 solution by 31P{1H}-n.m.r. spectroscopy, showed that the chemical shifts for the phosphorus atoms are slightly dependent on the pKa of the 4,4-(-X)2-2,2-bipy ligands. 相似文献

The dichloromethane solvates of the isomers tetrakis(μ‐1,3‐benzothiazole‐2‐thiolato)‐κ4N:S;κ4S:N‐dipalladium(II)(Pd—Pd), (I), and tetrakis(μ‐1,3‐benzothiazole‐2‐thiolato)‐κ6N:S;κ2S:N‐dipalladium(II)(Pd—Pd), (II), both [Pd2(C7H4NS2)4]·CH2Cl2, have been synthesized in the presence of (o‐isopropylphenyl)diphenylphosphane and (o‐methylphenyl)diphenylphosphane. Both isomers form a lantern‐type structure, where isomer (I) displays a regular and symmetric coordination and isomer (II) an asymmetric and distorted structure. In (I), sitting on an centre of inversion, two 1,3‐benzothiazole‐2‐thiolate units are bonded by a Pd—N bond to one Pd atom and by a Pd—S bond to the other Pd atom, and the other two benzothiazolethiolate units are bonded to the same Pd atoms by, respectively, a Pd—S and a Pd—N bond. In (II), three benzothiazolethiolate units are bonded by a Pd—N bond to one Pd atom and by a Pd—S bond to the other Pd atom, and the fourth benzothiazolethiolate unit is bonded to the same Pd atoms by, respectively, a Pd—S bond and a Pd—N bond. 相似文献

The relationship between bilevel optimization and multiobjective optimization has been studied by several authors, and there
have been repeated attempts to establish a link between the two. We unify the results from the literature and generalize them
for bilevel multiobjective optimization. We formulate sufficient conditions for an arbitrary binary relation to guarantee
equality between the efficient set produced by the relation and the set of optimal solutions to a bilevel problem. In addition,
we present specially structured bilevel multiobjective optimization problems motivated by real-life applications and an accompanying
binary relation permitting their reduction to single-level multiobjective optimization problems. 相似文献

The consequence of dynamical mass generation on the singularity structure of propagators is discussed. First the phenomena
of dynamical mass generation is discussed in the framework of Euclidean gap equations, then a possible Minkowski solution
is looked for. The examples are reviewed and studied for several models: Yukawa, QED, QCD and Wess-Zumino. It is argued that
the absence of propagator pole goes hand in hand with the nontrivial solution for mass function. The consequences are discussed. 相似文献

No quark candidates have been seen among 0.6 × 109 charged particles at the ISR. The corresponding cross-section limit for charge
for quark masses up to 22(13) GeV, assuming PT = 0.4 GeV/c. 相似文献

Palladium(II) chloride complexes of o-alkyl substituted phosphanes were prepared in various solvents with the phosphane ligands o-methylphenyldiphenylphosphane, o-ethylphenyldiphenylphosphane, o-isopropylphenyldiphenylphosphane, o-cyclohexylphenyldiphenylphosphane and o-phenylphenyldiphenylphosphane. The structures of the complexes were characterized by 1H NMR and 31P NMR spectroscopy and elemental analysis. The X-ray structures of PdCl2(o-methylphenyldiphenylphosphane)2, PdCl2(o-isopropylphenyldiphenylphosphane)2, PdCl2(o-cyclohexylphenyldiphenylphosphane)2, PdCl2(o-phenylphenyldiphenylphosphane)2, [PdCl2(o-methylphenyldiphenylphosphane)]2, [PdCl2(o-ethylphenyldiphenylphosphane)]2 and [PdCl2(o-cyclohexylphenyldiphenylphosphane)]2 were also determined. We report a systematic, solvent-dependent method to prepare palladium(II) complexes of the aryl phosphines o-methylphenyldiphenylphosphane, o-cyclohexylphenyldiphenylphosphane and o-phenylphenyldiphenylphosphane with a desired nuclearity. We demonstrated that chlorinated solvents promote the formation of dinuclear chlorine-bridged palladium complexes for all five ligands. The ligands preferentially form mononuclear palladium complexes in other solvents where the starting materials are only weakly soluble in the solvent. 相似文献

The preparation and structures of caesium lithium sulfate, Cs1.15Li2.85(SO4)2, and caesium lithium rubidium sulfate, Cs0.90Li2.88Rb0.22(SO4)2, are described and discussed in the context of simple and double sulfate polymorphism. The latter structure is related to the former through the substitution of Rb for Cs. In both crystals, the sulfate ions occupy two non‐equivalent sites, but the ions are disordered in Cs1.15Li2.85(SO4)2. 相似文献
