Abstract
The crystal and molecular structure of 2,9-di-(methylnitronato)-3,5,10,12-tetramethyl-1,4,8,11-tetraazacyclotetradeca-4,11-dienenickel(II) di-triethylammonium diperchlorate (2c) has been determined of the basis of X-ray diffraction data. The crystals are monoclinic, space groupP21/c,Z=2; cell constantsα=11.478(3),b=15.177(3),c=11.431(3) Å,β=99.34(2)°. The structure was refined (full matrix, least squares) with 3408 unique reflections givingR=0.0616. An octahedral configuration of the Ni(II) coordination sphere was found to consist of the macrocycle N4 atoms occupying the equatorial plane of the octahedron with the O-atoms of the nitronato groups in the apical positions. The triethylammonium cations are hydrogen-bonded to the remaining O-atoms of the nitronato groups.
