The simplest supramolecular complexes containing pairs of Mo_2(formamidinate)_3 units linked with various dicarboxylates:preparative methods,structures,and electrochemistry

摘要

Twelve compounds containing two quadruply bonde dMo_2(DAniF)_3 (DAniF=N,N'-di-p-anisylformamidinate) units linked by dicarboxylate anions have been prepared in high purity and good yields.All of these compounds have been charactewrized by crystallography and NMR.The dinuclea rpairs display electrochemical behavior which is controlled by the nature of the bridging dicarboxylate group.As described by the linkers,the compounds are oxalate,1;acetylene dicarboxylate,2; fumarate,3; tetrafluroophthalate,4;carborane dicarboxylate,5;ferrocene dicarboxylate,6;malonate,7;succinate,8;propane-1,3-dicarboxylate,9;tetrafluorosuccinate,10;bicyclo[1.1.1]-pentane-1,3-dicarboxylate,11;and trans-1,4-cyclohexanedicarboxylate,12.
