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。

Such parameters as ionic liquid catalyst system and H^+ proton donor, that affect the change of the organic phase and the mass of organic matter in residual phase of asphaltic sands, were investigated.

The initial interaction modes of pyreno[2,1-b]pyrrole and its dimeric derivative with F in MeCN can be understood as hydrogen-bonded complexes. Excess F ions promotes deprotonation of N-protons and results in the bathochromic changes in both absorption and fluorescence spectra.

实验过程中发现，在初始模式中，芘骈吡咯及双芘骈吡咯与氟离子形成氢键附合物；之后加入的氟离子，因其带有极强的碱性，将促使吡咯官能基中氮上氢进行去质子化，而造成吸收及萤光光谱的红位移现象。

The BAW detector combined with ion exclusion chromatography is used to determine short-carbon-chain organic acids in beehoney and beverages. NA and NAD in foods is also determined by IC-BAW.

The four reaction channels including hydroxyl-type benzaldoxime are endothermic reaction, thermodynamically non-spontaneous process, but the other four reaction channels including ion-type benzaldoxime participation are exothermic reaction and thermodynamically spontaneous process. The latter four reaction channels, which have lower reaction barriers, faster reaction velocities and bigger equilibrium constants than those of the former fours, are the chief reaction channels.

苯甲醛肟以羟基型参与反应的4个反应通道均为吸热反应和热力学非自发过程，它们均具有较高的反应势垒、较慢的反应速率和较小的平衡常数；而以离子型参与反应的四个反应通道均为放热反应和热力学自发过程，它们的反应势垒较低，反应速度较快，平衡常数也较大，故苯甲醛肟应主要以离子型参与反应。

A systematic study of Fe-ion doping in nanosized TiO2 is performed by measuring their photoreactivies in deradation of benzophenol. The presence of Fe-ion in the TiO2 crystalline significantly influences photoreactivity.
