A 0D vanadium borophosphate [Co(en)3]2[V3P3BO19][H2PO4]·4H2O (1) and two 1D vanadium oxides [Co(en)3][V3O9]·H2O (2) and [Co(dien)2][V3O9]·H2O (3) have been synthesized hydrothermally from the reaction mixture of V2O5-H3PO4-H3BO3-CoCl2-R-H2O at 110 
C (R: en or dien). The complex cations Co(en)33+ and Co(dien)23+ arecooperatively organized in the reaction medium to play a structure-directing role in the formation of the inorganicclusters and chains. The structures are determined by single-crystal X-ray diffraction analysis and further characterizedby X-ray powder diffraction, ICP, and TG analyses. The structure of 1 contains isolated [V3P3BO19]5- cluster anions,H2PO4- anions, racemic Co(en)33+ cations, and H2O molecules, which form a complex H-bond network. 2 and 3both contain chains of corner-sharing VO4 tetrahedra running along the 21 screw axis. The complex cations locatedin the interchain region interact with the chains through H-bonds. 2 is crystallized in an enantiomorphic spacegroup and only one enantiomer of Co(en)33+ is involved in the structure. Crystal data: 1, monoclinic, C2/c, a =32.8492(14) Å, b = 11.9601(3) Å, c = 22.6001(7) Å, 
= 108.9630(8), Z = 8; 2, orthorhombic, P212121, a =8.1587(16) Å, b = 12.675(3) Å, c = 18.046(4) Å, Z = 4; 3, monoclinic, P21/c, a = 16.1663(10) Å, b = 8.7028(3)Å, c = 13.9773(5) Å, = 103.1340(18), Z = 4.
