摘要
Three new vanadoborates [H(3)teta](3)[V12B18O54(OH)(6)(H2O)]center dot(H3O)center dot 5H(2)O (1, teta=triethylenetetramine), [H(4)teta](2)[V6B22O44(OH)(10)]center dot 4.5H(2)O (2) and [H(4)tepa](2)[V6B22O44(OH)(10)]center dot 4H(2)O (3, tepa=tetraethylenepentamine) have been hydrothermally synthesized and structurally characterized. 1 contains cage cluster [V12B18O54(OH)(6)(H2O)](10-) based on one puckered B18O36(OH)(6) ring sandwiched between two V6O15 clusters. Both 2 and 3 contain new decorated cage cluster [V6B22O44(OH)(10)](8-) built up from a central band of [V6O18] capped top and bottom by two raft-like polyborate [B11O20(OH)(4)] units. The magnetic susceptibility of 3 demonstrates the presence of antiferromagnetic interaction between V-IV cations. The theoretical band structure and spectroscopic properties have been also studied.
