Linkage isomerism in 4-(2-aminoethyl)morpholine (L) complexes of nickel (II) nitrite: X-ray single crystal structure of trans-[NiL2(NO2)2]

The linkage isomers trans-[NiL2(NO2)2] (brown, 1a) [L = 4-(2-aminoethyl)morpholine] and trans-[NiL2(ONO)2] (blue-violet, 1b) are synthesized and characterized.
