Abstract

[H2N(CH2)3NH3]2[MoO2(C10H6O2)2] (1) was synthesized by the reaction of (n-Bu4N)4[Mo8O26] with 2,3-dihydroxynaphthalene in the mixed solvent of CH3OH, CH3CN and 1,3-propanediamine. (C5H11N2)2- [H2N(CH2)3NH2][MoO2(C10H6O2)2] (2) was obtained by the reaction of Na2MoO4·2H2O with 2,3-dihydroxy- naphthalene in the same solvent above. Both of the complexes possess complex anion [Mo(VI)O2(OC10H6O)2]2− which shows pseudo-octahedrally coordinated fashion, while the counterions are two protonated 1,3-propanedia- mine in complex 1 and (C5H11N2)+ in complex 2. (C5H11N2)+ is the byproduct of reaction 2, which results from combination of acetonitrile with 1,3-propanediamine. Packing diagrams of the two complexes are also different. There is anti-parallel-aligned-double-meso-bilayer unit in complex 1. However there are four chiral anions arranged in anticlockwise orientation in complex 2.
