A novel proton transfer compound (a new molybdate salt) and its X-ray structure

A novel proton transfer compound (OHRNH3)22+(MoO4)2- (R = 2-methyl-1-propyl), derived from 2-amino-2-methyl-1-propanol and MoO2(acac)2, synthesized and characterized by 1H NMR, X-ray diffraction analysis, UV-Vis and FT-IR spectroscopy. The single crystal X-ray diffraction analysis revealed that intra- and intermolecular proton transfer from (MoO4H2) to (OHRNH2) results in the formation of a new molybdate salt that its fragments are connected through H-bonding and ion-pairing as shown in the X-ray crystal structure. This salt crystallizes in the space group P21/n P_1 of the monoclinic system, with four molecules per unit cell. The unit cell parameters are a = 13.6091(11) , b = 6.1049(5) , c = 17.0840(13) and β = 97.745(4)°.DOI: http://dx.doi.org/10.4314/bcse.v27i1.7
