Synthesis, Physicochemical Studies and Molecular Modeling of Some Zwitterionic Buffer Complexes

Abstract

Interaction of the zwitterionic buffer 3-(N-morpholinol)-2-hydroxypropane
sulfonic acid (H2MOPSO) with the divalent cobalt, nickel and copper
ions gave the solid [Co(MOPSO)(H2O)4].12H2O, [Ni(MOPSO)-(H2O)4].9H2O
and [Cu(MOPSO)(H2O)4].3H2O complexes. The complexes were characterized
by elemental analysis, mass and infrared spectrometry. The solid complexes
were also investigated by thermal (DTA and TG) analysis. Molecular modeling
of the complexes expected that the molecular geometry of the three complexes
could have distorted octahedral arrangements.
