By virtue of the coordination of Cr2L (L = CO; PPh3; C3H5 BF4-) with N-vinylcarbazole, acenaphthylene and their derivatives as organic ligands, a series of organometallic complexes have been synthesized. Their spectra characterization and X-ray diffraction analysis have been performed. It is found that this kind of complexes possesses an electronic structure with highly extensive π- delocalization.

本文首次采用生物素标记的花生凝集素对中华蚱蜢配子发生过程中细胞质膜的糖蛋白含有糖基Gal-β-(1，3-GalNAC进行了标记，旨在认识配子发生过程中细胞质膜糖复合物的形成与变化规律，探讨其所具有的功能。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。

At the beginning of the treatment with BF〓·Et〓O, the BF〓 will coordinate with the alkoxyl group to form intermediates, and the intermediates will then convert to the fluorinated products that generate more active species for styrene polymerization under the selected conditions.

在〓加入的开始时，BF〓和甲氧基形成配位中间体，然后此中间体转化成BF3配位的氟化物。

It was found that the asymmetric induction level of H〓-MAP was exclusively higher than that of corresponding MAP. Under the optimized reaction conditions, the allylation product could be obtained in up to 90.9% ee with H〓-MAP having 3, 5-xylyls as chiral inducer.

发现H〓-MAPs比MAPs类配体取得了更好的不对称诱导效果，在优化的反应条件下，可以得到90.9％ee值的产物，大大高于文献中报道的MAPs配体的最好结果（73％ee）。

The results indicated that the Fe3+ ion of Fe-AO-PAN was coordinated with three amino nitrogen atoms and three hydroxyl oxygen atoms of three amidoxime units on the surface of AO-PAN by covalent bond, and the coordination number was six.

结果表明， Fe-AO-PAN中的Fe3+能够与AO-PAN表面三个偕胺肟链节单元的三个氨基氮原子和三个羟基氧原子进行配位反应，配位数为6。

The Mo center of [Mo8](superscript 4)-shows a slight distorted square antiprism coordination environment. The N atoms of cyano groups, acting as acceptors of hydrogen bonds, together with protonate N atoms from organocations and the lattice water, serving as donors of hydrogen bonds, form intricate hydrogen bond interactions, thus generating three-dimensional supramolecular network with the help of π-π interactions of some organocations.

Mo8(上标 4-)离子中，Mo中心处于扭曲的反四棱柱配位环境。8个未配位的氰基氮原子作为氢键的受体，有机阳离子上质子化的氮原子和结晶水作为氢键的给体，形成了丰富的氢键作用，这些氢键作用连同部分有机阳离子间的π-π堆积、阴阳离子间的静电力和Van Der Waals力构筑成三维超分子网络。

The neighbor-ing two Gd3+ ions are connected by two simple bridged carboxyl groups and a μ2-bridging carboxylgroup. Each G-d3+ ion is simuetaneosly coordinated by two water molecules. So the coordination num-ber of Gd3+ is nine, forming a coordination polyhedron of distorted mono capped square antiprism.

相邻Gd3+离子通过2个简单羧基桥和1个μ2羧基桥联结起来，还有2个水分子配位于每个Gd3+离子，所以Gd3+的配位数为9，形成变形的单帽四方反棱柱体。
