In the title compound, [Co(C 11 H 9 ClN 3 O 2 ) 2 ]Á2.5H 2 O, the Co II atom, which lies on a twofold rotation axis, is coordinated by four N atoms and two O atoms from two ligands in a distorted octahedral geometry. In the crystal structure, molecules are linked together by intermolecular O-HÁ Á ÁO

## Abstract The structures of the six isomers of 2,3,5,6‐tetramethyl‐morpholine have been determined by means of proton nuclear magnetic resonance studies at 100 MHz. The spectra have been analysed in terms of spin–spin coupling constants and population distributions of the possible conformers at l
