preparation and molecular structure of [cucl(l)]6; l= 2-(methylamino)pyridine

the 2-(methylamino) pyridine, l, reacts with cucl in thf to give hexameric copper (i) complex, [cucl(l)]6. the molecular structure has been determined by using single-crystal x-ray diffraction method. the complex crustallizes in the monoclinic space group p21/n with four molecules per unit cell. the unit cell dimensions are a = 8.3495 (15), b = 15.622 (6), and c = 17.030(4) å with b= 98.55 (2)°. the final r value is 0.062 for 4261 reflections measured. coordination number around cu(1) and cu(3) is four (nearly tetrahedral), but around cu(2) is three (nearly trigonal). the cu(2)-cu(3) bond distance is 2.682 (2)å.
