866-871
The synthesis, spectral characterization, single crystal structure and properties of a new potassium coordination polymer [K(LH2)(MoO4)] 1 (LH2 = 1,3-dihydroxy-2-(hydroxymethyl)propan-2-aminium) are reported. The bimetallic compound 1 crystallizes in the non-centrosymmetric trigonal P3c1 space group with K+, (LH2)+ and (MoO4)2– located on three-fold axes. The K+ ion exhibits hexa coordination and both (LH2)+ and (MoO4)2– function as μ3-bridging tridentate ligands resulting in the formation of a three-dimensional (3D) polymeric structure. In the 3D polymer, the {KO6} octahedra and {MoO4} tetrahedra are interlinked into a hexagonal array of alternating {KO6} and {MoO4} polyhedra connected via corner-sharing with enclosure of (LH2)+ ion in the cavity. The (LH2)+ and (MoO4)2– units in 1 are interlinked with the aid of three varieties of hydrogen bonding interactions. Thermal decomposition of 1 at 600°C results in the formation of K2Mo2O7. Comparative structural chemistry of several (LH2)+ containing compounds is described |
