环式空间

But in the + moiety, the three benzimidazole rings shared the whole space equally, the dihedral angel among them is about 120°, just like three fan blades of an airscrew, the molecular structure appear gear-like shape.

X-射线单晶衍射测试、红外、紫外等方法确定了三(2-苯并咪唑亚甲基)胺的Fe和Co配合物的结构，由晶体结构发现金属配位情况不同、配合物在结构上存在着差异，Fe为八面体构型，而Co为三角双锥构型；其次，两配合物中的苯并咪唑环间夹角不同，配合物中包含N2和N4的两个苯并咪唑环间夹角仅为9.41(0.11)，几乎构成一个平面，呈蝴蝶形；后者Co三个苯并咪唑环几乎平分了整个空间，它们之间的夹角约为120，呈三扇叶螺旋桨式构型，为齿轮形。

The Xray diffraction analysis of the compounds (3) and (4) shows the presence of an intramolecular coordination of oxygen to the tin atom giving rise to a fivemembered ring in which the metal exhibits a distorted trigonal bipyramidal geometry.

并通过X-射线衍射测定了（3）和（4）的晶体结构，其空间群均为P2〓/c，晶胞内分子数Z=4，分子结构是以锡原子为中心金属原子、含分子内O→Sn配位键五员环的扭曲三角双锥结构，碳碳双键的两个氢是顺式构型。

The X-ray crystal structure analysis of the complexes shows that all lanthanidecomplexes exhibit a tripodal ligand coordination mode, with three imino nitrogenfrom benzimidazolyl and pyridyl group, and one amino nitrogen atoms as donors.The ligands show two kinds of configuration: the fan-like and the pincer-like. Bothintra- and intermolecular π-π interactions are found in these complexes.

晶体结果表明，在所有的稀土配合物中，三脚架配体均用三个支脚上的苯并咪唑、吡啶环氮原子及一个顶端的氮原子和稀土离子进行配位，表现出三脚架式配位方式，同时，三脚架配体有风扇形及钳子形两种空间配位构型，并形成了分子内及分子间的π-π堆积作用。

Controls on the stage the 2-DIN sound main engine and air-conditioning system's pressed key or elects Niu to be very big, the use and the operation facilitate to start from the front seat, to pick the aerosol -like gear place design very abundant, the special modelling design platoon document pole feel quite good, and changes the tradition row of document location large-scale double sets the cup frame, the outer ring is equipped with the blue color cold light illumination, is sending out the light technical feeling at night; But the very abundant front seat central arm rest except internal sets at the space, place above and is equipped with the info clerk box which may turn forward.although tries the vehicle crew to attempt puts in 80G iPod Classic is unable successfully, the domestic introduction very abundant has not provided the AUX-IN external connection sound source or the blue bud exempts holds the communication function, but still might do for goods and so on info clerk handset.

从前座开始，采悬浮式排档座设计的酷博，特殊造型设计的排文件杆手感颇佳，并将传统排文件位置改为大型双置杯架，外环设有蓝色冷光照明，在夜间散发着淡淡的科技感；而酷博的前座中央扶手除内部的置物空间，上方并设有可向前翻起的收纳盒。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
