Synthesis, Crystal Structure and Antibacterial Activity of Two Hydrazones Derived from 2-Fluorobenzhydrazide

Two new Schiff base benzoyl hydrazone compounds, C14H10FN3O3 (Ⅰ) and C14H10F2N2O (Ⅱ), have been synthesized and characterized by elemental analysis, IR, UV and X-ray single-crystal diffraction. Both compounds crystallize in monoclinic, space group P21/c with a = 7.0514(14), b = 25.928(5), c = 7.7099(15), β = 111.823(2)°, V = 1308.6(4)3, Z = 4, C14H10FN3O3, Mr = 287.25, Dc = 1.458 g/cm3, μ(MoKα) = 0.115 mm-1, F(000) = 592, the final R = 0.0841 and wR = 0.2489 for 1901 observed reflections (I > 2σ(I)) for I; a = 11.232(3), b =12.735(4), c = 8.612(2) , β = 90.869(3)°, V = 1231.7(6)3, Z = 4, C14H10F2N2O, Mr = 260.24, Dc = 1.403 g/cm3, μ(MoKα) = 0.111 mm-1, F(000) = 536, the final R = 0.0453 and wR = 0.1085 for 1317 observed reflections (I > 2σ(I)) for Ⅱ. The antibacterial activities of both compounds against two bacteria were first studied and one compound showed considerable antibacterial activity against K. Pneumonia and S. aureus.     

高校教师绩效工资管理系统的设计与实现

高校教师绩效工资管理系统的设计得益于管理科学与信息技术的有机结合,并基于高校教师的职业与人事管理特征有效实现管理自动化、信息透明化、公平效率化的设计初衷。系统通过几个主要功能模块的分工与流程,结合系统的参数设置与运算,可以自动生成教师的绩效津贴。从而实现高校有限资源的优化配置与绩效工资的合理分配,在激励教职员工爱岗敬业、自我实现的同时,实现教师个人与高校优势互补、和谐共进的多赢局面。
