• Resumen

  • The reaction of both tris(2-aminoethyl)amine and tris(2-dimethylaminoethyl)amine with Zn(ClO4)2 in the presence of equimolar amount of NaBPh4 in methanol afforded two different zinc(II) complexes, namely ({[tren]Zn(HOMe)} · ClO4 · BPh4) 1 and ({[trenMe6]Zn} · ClO4 · BPh4) 2. Zinc(II) Complex 1, which has been structurally characterized by X-ray crystallography, takes up CO2 in methanol in the presence of base to fix it into monomethyl carbonato complex ({[tren]Zn(OCO2Me)} · BPh4 · 2MeOH) 3.
