Three new vanadoborates functionalized with zinc complexes

Three new vanadoborates [Zn4V10B34O84H10](H2dap)4(dap)2·9H2O (1), [Zn(H2teta)2V12B18O54-(OH)6]·4H3O (2) and [Zn(H3tepa)V12B18O54(OH)6][H2en]2·H3O·3H2O (3) have been hydrothermally synthesized and structurally characterized. 1 consists of new cluster [Zn4V10B34O84H10]8 − with the rare [Zn4B4O18] unit, protonated H2dap2 +, free dap and H2O molecules. Both 2 and 3 contain [V12B18O54(OH)6(H2O)]10 − clusters, which are connected by [Zn(H2teta)2]2 +/[Zn(H3tepa)]2 + groups as bridges into 1-D chain. The magnetic susceptibility of 3 shows the antiferromagnetic interaction between VIV cations.
