Linkage isomerism in 4-(2-aminoethyl)morpholine (L) complexes of nickel(II) nitrite: X-ray single crystal structure of trans-$NiL_{2}(NO_{2})_{2}$

摘要

The linkage isomers trans-bis[4-(2-aminoethyl)morpholine]dinitronickel(II) (brown, 1a) andtrans-bis[4-(2-aminoethyl)morpholine]dinitritonickel (II) (blue-violet,1b) have been synthesized from solution. Complex la is the major and thermodynamically controlled product, where as, complex 1b is minor and kinetically controlled product. The X-ray single crystal structure analysis of complex la has been performed.
