PREPARATION AND MOLECULAR STRUCTURE OF 2-BENZYLAMINOPYRIDINE COPPER(1) COMPLEX

Abstract
2-Benzylaminopyridine (HBAP) reacts with NaH in THF and generates the
sodium salt (NaBAP). Further reaction of [Cu(TMEDA) ] [CuCl ] with one
equivalent of this ligand in THF leads to the formation of a dimeric Cu(1)
complex, [Cu (BAP)] . H 0. The molecular structure has been determined by
using a single-crystal X-ray diffraction method. The yellow compound
crystallizes in the monoclinic space group P2 lc with four molecules per unit
cell. The unit cell dimensions are a = 8.090(4), b = 1 1.220(7), c = 22.412(8)?
with ?=91.3 l(3)?. The final R value is 0.065 for 3859 reflections measured.
Coordination number around each copper is two (nearly linear). The Cu ... Cu
distance is 2.4558(16) ? .
