| Abstract: | N3P3Cl6 reacts with 2-(aminomethyl)pyridine under formation of the stable geminal difunctionalized compound gem-N3P3Cl4(NHCH2(C5H4N)-2)2 1 . The chlorine atoms can be substituted by reacting 1 with sodium phenoxide to yield gem-N3P3(OC6H5)4(NHCH2(C5H4N)-2)2 2 . A vicinal di(pyridylmethylamino)-substituted compound, vic-N3P3(OC6H5)4(NHCH2(C5H4N)-2)2 3 can be obtained from the reaction of vic-N3P3(OC6H5)4Cl2 with 2-(aminomethyl)pyridine. Decomposition to Cu(NH2CH2(C5H4N)-2)2(NO3)2] 4 occurs when 1 is exposed to copper(II) nitrate · H2O. By contrast, 2 forms the stable copper complex Cu(NO3)2 · ( 2 )] 2 a in which the copper atom is bonded to three nitrogen atoms of the new chelating ligand and three oxygen atoms of the unsymmetrically coordinated nitrate groups. The structures of 1 , 2 , and 2 a were determined by X-ray crystallography. |
