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

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) ? .
