Novel organic-inorganic layered compounds derived from simple coordination building blocks:: Synthesis and structural characterization of (H3NCH2CH2NH3)[Fe(C2O4)MoO4] and Fe(H2NCH2CH2NH2)MoO4

Two new hybrid organic-inorganic compounds (H(3)NCH(2)CH(2) NH(3))[Fe(C(2)O(4))MoO(4)] (1) and Fe(H(2)NCH(2)CH(2)NH(2)) (2) were synthesized by the hydrothermal reaction between Fe(C(2)O(2)) . 2H(2)O, molybic acid, and ethylenediamine, The structure of 1 consists of 2-D layers formed by [Fe(C(2)O(4))MoO(4)](2-) nets with H(3)N(+)CH(2)CH(2)N(+)H(3) dications situated in the gaps, The structure of 2 features a double-layered structure formed by FeMoO(4) units that are capped by cis-coordinated H(2)NCH(2)CH(2)NH(2) molecules.
