A 0D anadium borophosphate [co(en)_3]_2[V_3P_3BO_19][H_2PO_4](1) centre dot4H_2O and 1D vanadium Oxides[Co(en)_3][V_3O_9)(2) cnetre dot H_2O and [Co(dien)_2][V_2O_9]centre dot H_2O(3)have been synthesizedhydrothermally form the reacton mixture f V_2O_5-H_3PO_4-H_3BO_3-CoCl_2-R-JH_2O at 110 deg C(R:en or dien).the coplex cations Co(en)~3+_3 and Co(dien)~3+_2 are cooperatively organized in teh reaction medium to play a structure-directing role in he formation of the inorganic clusters and chains.the structures are detrmined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction,ICP,and TG analyses.The structure of 1 contains isolated [B_3P_3BO_19]~5- clusteranions,H_2PO~-_4 anions,racemic Co(en~3+_3 ctions,and H_2O molecules,which form a complex H-bond network.2 and 3 both contain chains of corner-sharing VO_4 tetrahedra runningalogn the 2_1 screw axis.The complex cations located in teh interachain region itneract with the chains through H-bonds.2 is crystallized in an enantiomorphic space group and only one enantiomer of Co(en)~3+_3 is involved in the structure.Crystal data:1,monoclinic,C2/c,a=32.8492(14),b=11.9601(3)A,c=22.6001(7)A,beta=108.9630(8)deg,Z=8;2,orthorhomibic,P2_12_12_1,a=8.1587(16)A,b=12.675(3)A,c=18.046(4)A,Z=4;3,monoclinic,P2_1/c,a=16.1663(10)A,b=8.7028(3) A,c=13.9773(5)A,beta=10340(18)deg,Z=4.
