Abstract: Two novel complexes(C6H14 N5O)4 [H2V10 O28 ] ·9H2O(1) and (C6H14 N5O)6 [V10 O28 ] ·4H2O(2) were synthesized by the self-assembly of decavanadate and ABOB in aqueous medium at different pH values for the first time. Their structures were determined by means of IR, 51V NMR and X-ray diffraction. Complex 1 crystallizes in the monoclinic system,space group P21/n with a= 1.339 58(8) nm ,b=1.482 62(9) nm,c=1.713 53(14) nm,β=111.450(3)°,V=3.167 5(4) nm3,Z=2,R1=0.050 0,wR2=0.143 4. Complex 2 crystallizes in the monoclinic system,space group P21/n with a=11.698 8(7) nm,b=2.407 94(11) nm,c=1.313 20(10) nm,β=91.635(2)°,V=3.697 8(4) nm3,Z=2,R1=0.039 7,wR2=0.100 8. The X-ray crystallographic study shows that the crystals are constructed by electrostatic forces and hydrogen bond interactions among decavanadate anions,protonated ABOB cations and lattice water molecules. The polyanions,cations and water molecules arrayed in a good order to form 2D layered arrangements along the c axis in complex 1. The antibacterial trial shows that the two complexes show an good antibacterial activity against Staphylococcus aureus,Staphylococcus epidermis,MRSA and MRSE.
