The central 5, 5'-disubstituted bipyridine units of each ligand coordinate theNi or Fe ion, while all the terminal 6-monosubstituted bipyridine units of the ligands keep free of coordination, as the result trinuclear triple-stranded helicate 〓 can not form. This is considered to be caused by the steric hindrance of the methylene substituents α to the chelating nitrogens of the terminal bipyridine units and the strain caused by linkage mode.

配体L〓与Ag作用得到〓，两个配体链相互缠绕着两个Ag离子周围形成双股螺旋结构并以头尾式排列(见图3)，由于配体中位于配位N原子α或β位的末端甲基或次甲基取代基的空间位阻阻碍了头对头式异构体的形成，也正是由于配体头尾式排列而使Ag双股螺旋得以形成，这一结果表明该螺旋体的组装过程中自发地采取了空间阻碍尽可能小的那个构型。

Barker is synchronized code in digital communication. In this paper, design methods of barker 7 data transmitting card arc presented. The application background of Barker are introduced. The used methods of MCU 80C196KB and CPLD EPM7128SLC are set forth. Transmitting card is designed and implemented by using interface circuit and above-mentioned chips. The control process of barker 7 is introduced under PC parallel-port EPP mode. The partial design circuit is given, the cards is proved to achieve the generation and output of 7 Barker through practice. it can satisfy testing requirements of a certain Russian-made airborne product.
