Abstract
Abstract Solutions of copper(II) β-diketone complexes in CH2Cl2 or CHCl3 react with 2-(aminomethyl)pyridine (AMP) to produce Cu(AMP)3 2 +, which precipitates as its chloride salt. mer-[Cu(AMP)3]Cl2·CH2Cl2 is monoclinic, space group P21/c; a = 11.072(1), b = 22.306(3), c = 11.388(2) A; β = 117.39(2)°; Z = 4; R = 0.076; R w = 0.068 for 375 parameters and 3477 reflections with I > I σ (I). The mer-Cu(AMP)3 2 + ion has a tetragonally distorted octahedral geometry; distances from Cu to two trans-oriented pyridine N atoms are elongated (2.420(5) and 2.437(5) A), while the third is normal (2.060(4) A). Distances from Cu to the equatorial NH2 N atoms range from 2.012(5) to 2.048(5) A. The chloride ion in this compound is produced by nucleophilic attack of AMP on the CH2Cl2 solvent.
