Abstract
The (C2H10N2)[ Mn2(HPO4)3(H2O)]
and (C
H
N2)[ Mn3(HPO3)4] (n= 2-8) compounds
were synthesized by using mild hydrothermal conditions under autogeneous
pressure. The phosphate and phosphite phases show a layered structure with
the alkyldiammonium cations located between the sheets. The emission and
excitation luminescent spectra are in accordance with the presence of Mn(II)
high spin cations in slightly distorted octahedra. The magnetic measurements
of both kinds of compounds indicate the existence of antiferromagnetic
interactions.
