Especially,the subbranch of enterobacteriaceace made again four small branches as genus taxon.This tree also shows that bacilliform bacterium is distinct from each other in the NJ and MP trees.After all species on the tree are merged,the topological configuration of the unrooted tree of 16S gene is closed to that of the host range unrooted tree.However,the position of bacillus is greatly changed on both the unrooted trees.

The title compound,(C6H6N3)(subscript 4)[Mo8]H2O, crystallizes in the triclinic system with Pī space group, the asymmetry unit of which is composed of one [Mo8](superscript 4)-anion, four protonate benzotriazolium organocations and a lattice water.

化合物(C6H6N3)4[Mo8]H2O的晶体结构属于三斜晶系的P1空间群，其不对称单元由1个[Mo8](上标 4-)，4个质子化的苯并三唑有机阳离子C6H6N3和1个结晶水组成。

Their electrochemical behaviors are similar to that of TTF, so they should be good donors for conducting materials. They are novel monosubstituted asymmetric TTF-π-A donor molecules with TTF cores, which should be good donors for molecular conductors or OFET potential application.2. The tuning of the charge-transfer of TTF-PEO by solvent was realized forming the mono- and dication complexes_2CuBr_4 (5) and_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6) in the triclinic Pīand the orthorhombic Pbca space group, respectively.

同时每种化合物均为单取代的非对称分子，因此该类化合物在非线性光学材料领域可能有潜在的应用。2、通过改变溶剂的方法方便地实现了调节TTF-PEO的电荷转移量为+1和+2，分别合成出化合物_2CuBr_4 (5)和_2(CuBr_4)_2·CH_2Cl_2·CH_3CN (6)，晶体结构分析表明它们分别属于三斜的Pī和正交的Pbca空间群。
