  摘要：

  合成了一系列五种2-杂芳腈氧肟酸，包括：α-氧肟基-(2-苯并咪唑基)乙腈（HBIHCO）、α-氧肟基-(N-甲基-2-苯并咪唑基)乙腈（HBIMCO）、α-氧肟基-(2-苯并噻唑基)乙腈（HBTCO）和α-氧肟基-(2-喹啉基)乙腈（HQCO）以及它们的单价铊(I) комплексы。采用光谱方法（1H、13C NMR、红外、紫外可见、质谱）和X射线分析对其进行了表征。HBIMCO（作为单水合物）在固态中采用平面反式反式构型。“HBOCO”的晶体结构揭示了存在亚硝基阴离子a（BOCO−）和质子化的氧肟阳离子b（H2BOCO+），它们在单元胞中形成氢键二聚体。这两种分子均采用平面结构，但配置不同：分子a为顺反构型，而b为反式反式构型。这是首次报告在氧肟中发现了两亲离子对，并且同一晶体中共存的两种几何顺/反异构体。所有2-杂芳腈氧肟酸在去质子化后形成黄色阴离子，在溶液中表现出显著的负溶剂色变效应。在Tl2CO3的热水溶液与固态质子化2-杂芳腈氧肟酸HL之间发生的非均相反应生成黄色的TlL。Tl(BTCO)的晶体结构显示形成了中心对称的二聚体，这些二聚体相互连接形成双链一维配位聚合物。氧肟基团的氧原子在三个不同的铊(I)中心之间起桥接作用。该阴离子在复合物中是非平面的，并采用反式反式构型。复杂中的聚合物结构呈现梯子型结构。苯并噻唑基之间错叠的π–π相互作用为结构提供了额外的稳定性。无论是有机配体还是它们的Tl(I)复合物在固态下均表现出强烈的室温蓝色发光。

  A process for protecting cultivated plants against aggressive agricultural chemicals is described in which oxime derivatives of the formula ##STR1## are used as antidotes. Either the cultivated area for the cultivated plants or the cultivated plants themselves or parts of the plant (seeds, tubers, stem parts and the like), as desired, can be treated with these oxime derivatives, which are used as a dressing.

• Light Insensitive Silver(I) Cyanoximates As Antimicrobial Agents for Indwelling Medical Devices

  Ten silver(I) cyanoximates of AgL composition (L = NC-C(NO)-R, where R is electron withdrawing groups: -CN, -C(O)NR2, -C(O)R' (alkyl), -C(O)OEt, 2-heteroaryl fragments such as 2-pyridyl, 2-benzimidazolyl, 2-benzoxazolyl, 2-benzthiazolyl) were synthesized and characterized using spectroscopic methods and X-ray analysis. Crystal structures of four complexes were determined and revealed the formation of two-dimensional (2D) coordination polymers of different complexity in which anions exhibit bridging or combined chelate and bridging binding modes. In these compounds, anions are in the nitroso form. All studied AgL complexes are sparingly soluble in water and are thermally stable to 150 degrees C Synthesized compounds demonstrated remarkable insensitivity toward visible light and UV-radiation, which was explained based on their polymeric structures with multiple covalent bonds between bridging cyanoxime ligands and Ag(I) centers. All 10 silver(I) cyanoximates were tested in vitro on the subject of their antimicrobial activity against both Gram-positive and Gram-negative microorganisms such as Escherichia coli, Klebsiella pneumoniae, Proteus sp., Pseudomonas aeruginosa, Enterococcus hirae, Streptococcus mutans, Staphylococcus aureus, and Mycobacterium fortuitum as well as against Candida albicans in solutions, and in the solid state as pressed pellets and dried filter paper disks presoaked with solutions of AgL in DMF. Results showed pronounced antimicrobial activity for all investigated complexes. A combination of five factors: (1) light insensitivity, (2) poor water solubility, (3) high thermal stability, (4) lack of toxicity of organic ligands, and (5) in vitro antimicrobial activity allows development of silver(I) cyanoximates for medical applications. These include antimicrobial additives to acrylate glue, cured by UV-radiation, used in introduction of prosthetic joints and dental implants, and prevention of biofilm formation on several types of indwelling medical devices.
