Nucleophilic attack on dichloromethane. Synthesis and structure of mer-[cu(2-(aminomethyl)pyridine)3]2+
Solutions of copper(II) β-diketone complexes in CH2C12 or CHC13 react with 2-(aminomethyl)pyridine (AMP) to produce Cu(AMP)32+, which precipitates as its chloride salt. mer-[Cu(AMP)3]Cl2*CH2Cl2is 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; Rw= 0.068 for 375 parameters and 3477 reflections with/ Iσ(l). The mer-Cu(AMP)32+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 NH2N 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 CH2C12 solvent. © 1990, Taylor & Francis Group, LLC. All rights reserved.
