dc.description.abstract	The synthesis, crystal structure, redox characteristics and photochemistry of a new heptamolybdate supported magnesium-aqua coordination complex viz. (hmtH) sub(2) [{Mg(H sub(2)O) sub(5)}sub(2) {Mo sub(7) O sub(24)}].3H sub(2)O 1 (hmt = hexamethylenetetramine) is reported. The cyclic voltammogram reveals quasireversible redox behaviour while the degradation of rhodamine B (RhB) by 1 under sunlight irradiation indicates its photocatalytic activity. In the crystal structure of 1, two [Mg(H sub(2)O) sub(5)] sup(2+) units are linked by a mu sub(2)-bridging bidentate hepta- molybdate ligand resulting in a heptamolybdate supported magnesium-aqua coordinated dianionic complex [{Mg(H sub(2)O) sub(5)}sub(2) {Mo sub(7) O sub(24)}]sup(2?) charge balanced by two (hmtH) + cations. The cations, anions and the lattice water molecules are linked by several hydrogen bonding interactions.	en_US
