络合物

The 3d transition metal monoxides coordinate one noble gasatom in forming the linear NgMO(M=Cr, Mn, Fe, Co, Ni; Ng=Ar, Kr, Xe) complexes.(3) The group VB metal oxides MO_2 and MO_4 coordinate two and one noble gasatoms in forming the MO_2_2 and MO_4(M=V, Nb, Ta; Ng=Ar, Kr, Xe)complexes.

3第VB族金属二氧化物与两个稀有气体原子形成的MO_2_2(M=V，Nb，Ta；Ng=Ar，Kr，Xe)络合物，其四氧化物与一个稀有气体原子形成的MO_4(M=V，Nb，Ta；Ng=Ar，Kr，Xe)络合物。

The rhodium complex with TPPTS ligand was immobilized in ionic liquid, so the catalyst was easy separated by decantation and reused in next run.

带有强极性基团的膦配体TPPTS 和离子液体之间有很强的作用力，可将Rh/TPPTS 络合物"固定"在离子液体中，有效防止了催化剂的流失。

Large single crystals were also obtained by using pyrocatechol as additive. It was shown by 〓Si-NMR and IR that Sipyrocatechol complex was formed in the reaction system.

在F〓体系中，F〓对铝源和硅源起络合和矿化作用，形成可溶性氟硅酸盐AlF〓〓、SiF〓〓络合物，然后缓慢水解成含氧氟硅酸盐络合物，它们再发生定向缩聚，提供了分子筛晶体生长所需的可溶性结构单元。

Due to the increasingly deep concerns about the cytotoxicity of stannous octoate, which is the most widely used catalyst for synthesizing polyesters derived from lactides (L-LA, D, L-LA, GA) via ring opening polymerization, a lot of new metal complexes of relatively low toxicity including Schiff base–Al complexes, Red-Al were developed and used to initiate the living, stereo-specific, and/or stereo-selective ROP of lactides.

由于合成聚乳酸类生物医用降解材料的最常用的催化剂辛酸亚锡 Sn2的细胞毒性问题已在世界范围内引起日益深切的关注，近年来国内外学者已研究开发出许多性能优异的低毒、非锡金属络合物催化剂（如：位阻西佛碱-Al 络合物， Red-Al 等）用于催化交酯类单体的活性、立构专一性及立构选择性聚合反应。

It was found that earlytransition metal monoxides ScO, TiO and VO do not form noble gas complexes, whilethe late transition metal monoxides coordinate one noble gas atom in forming thelinear NgMO(M=Cr, Mn, Fe, Co, Ni) complexes.

对于前过渡的ScO，TiO和VO分子，它们的9σ，1δ和4π价分子轨道能量很高，不能有效地与稀有气体原子形成络合物，而对于后过渡金属一氧化物则可以配位一个稀有气体原子形成直线型的NgMO(M=Cr，Mn，Fe，Co，Ni)络合物。

People in that country like nude swimming.
