摘要：

Two zinc(II) hexaborate(2-) complexes, [Zn{O-3-B6O7(OH)(6)}(N-3-dien)]0.5H(2)O (dien = NH(CH2CH2NH2)(2)) (1) and (NH4)(2)[Zn{O-2-B6O7(OH)(6)}(2)(H2O)(2)]2H(2)O (2), and a zinc(II) dodecaborate(6-) complex, (1,3-pnH(2))(3)[(N-1-H3N{CH2}(3)NH2)Zn{O-3-B12O18(OH)(6)}](2)14H(2)O (1,3-pn = 1,3-diaminopropane) (3), have been synthesized and characterized by single-crystal XRD studies. The complexes crystallized through self-assembly processes, from aqueous solutions containing 10:1 ratios of B(OH)(3) and appropriate Zn(II) amine complex: [Zn(dien)(2)](OH)(2), [Zn(NH3)(4)](OH)(2), and [Zn(pn)(3)](OH)(2). The hexaborate(2-) anions in 1 and 2 are coordinated to octahedral Zn(II) centres as tridentate (1) or bidentate ligands (2) and the dodecaborate(6-) ligand in 3 is tridentate to a tetrahedral Zn(II) centre.
