Abstract
In Ni([13]aneN4)(teb)2 (1) axial long-range interaction with the teb a nions leads to bipyramidal coordination of Ni (coordination number 4+2 ), whereas in 1,4,8,11-tetraazaundecanenickel bis-tetraethynilborate, [Ni(2,3,2-tet)teb]teb (2) only one of the teb anions is involved in co ordination. Shortening of the equatorial Ni-N bond by 0.1 angstrom in 1 compared with 2 leads to elongation of the axial secondary bonds by about 0.6 angstrom.
