  complex molecule
The linear dependence of the degradation rate constant of the triplet-triplet complexes to the ground-state molecules on [Q]2 suggests that two quencher molecules are necessary for the quenching of one complex molecule.
      
The whole complex molecule is composed of two close parts in which every one has a nine-coordination structure as a distorted monocapped square antiprism.
      
The whole complex molecule is composed of two close parts in which every one has a nine-coordination structure as a distorted monocapped square antiprism.
      
Complex molecule I consists of the central binuclear anion [Cu2Br6]2- and two peripheral cations K(18-crown-6)]+ of the host-guest type bound to the [Cu2Br6]2- anion through two and one K-Br coordination bonds.
      
The octahedral complex molecule [NiBr2(H2O)4] and the [H2(Crypt-222)]2+ dication (with two protonated N atoms) are located around the inversion center; the latter is statistically disordered.

EHMO method is applied to caloulate the total energies of the alkane coordinated to mixing orbital d_(z~2)/d(x~2-y~2) of catalytic active species PtCl_3(H_3O)~-. The results show that end-on coordination is more advantageous than side-on coordination. Furthermore, the same method is used to calculate both the barrier petential of formation of a rate-determining intermediate and the change of net charges of principal atoms, the results show that the rate-determining step is not a simple exchange reaction, but...

Furthermore, the same method is used to calculate both the barrier petential of formation of a rate-determining intermediate and the change of net charges of principal atoms, the results show that the rate-determining step is not a simple exchange reaction, but an intramolecular reductive-elimination of the binuclear complex.

本文用EHMO法计算了饱和烃以端基及侧基配位到催化剂活性种PtCl_3(H_2O)~-的d_(z~2)/d_(x~2-y~2)混合轨道上体系的总能量.结果表明,以端基的方式进行配位较之侧基有利.还计算了反应速率控制步骤中生成过渡态的势垒和主要原子的净电荷的变化,从而阐明了控制步骤的机理是双核配合物分子内靠近氢根配体的桥联氯离子转移到烷基上的还原消去反应.理论计算与实验结果一致.

Extraction chemistry of copper by aromatic hydroxyoximes has been extensivelyinvestigated by various authors. The organic extractants used in such studies, as arule. were a mixture of geometric isomers i. e. a mixture containing both syn-andanti-isomers. Previous studies in this laboratory indicated that both geometric isomersof 2-hydroxy-4 (5)-substituted benzophenone oximes could be separated successivelyby recrystallization of their copper complexes and followed by column chromatographyon silica gel.

Extraction chemistry of copper by aromatic hydroxyoximes has been extensivelyinvestigated by various authors. The organic extractants used in such studies, as arule. were a mixture of geometric isomers i. e. a mixture containing both syn-andanti-isomers. Previous studies in this laboratory indicated that both geometric isomersof 2-hydroxy-4 (5)-substituted benzophenone oximes could be separated successivelyby recrystallization of their copper complexes and followed by column chromatographyon silica gel. The present paper deals with a mechanistic study of the extraction ofcopper by the anti-isomers of 2-hydroxy-4(5)-substituted benzophenone oximeswhich were known to be the active principle of such extractants. By Job's and slope method as well as by the method of saturated extraction andelemental analyses the composition of the complexes formed by the anti-isomers ofaromatic hydroxyoxime and copper was deduced as 2:1 ligand-metal. Based on UV, IR and molecular weight determination the structures of thecomplexes were elucidated. As the central copper atom is linked with phenolic oxygenand oximido-nitrogen by covalent and coordinated bonds respectively, whereas theoximido hydroxy group forms stronger intramolecular hydrogen bonds with thephenolic oxygen of another ligand molecule. The resulting molecule seems to be inplanar square configuration.

The formation of Si-N bond from ligating dinitrogen of tungsten dinitro-gen coordination compound is reported for the first time. The dinitroge n coordination compound cis-[W(N2)2 (PMe2ph)4] reacts with Me3SiI at 50℃ to give[WI(N2SiMe3)(PMe2ph)4], which is further converted into [WI2(N2HSi-Me3) (PMe2ph)3] by treatment with HI. The molecular structure of the latter coordination compound has been determined by X-ray crystallographic analysis, which clearly shows the Me?Si-group bonded to the B-position from the...
