Abstract
The synthesis and characterization by single-crystal X-ray diffraction (XRD) studies of two new zinc(II) hexaborate(2−) complexes, [Zn(en){B6O7(OH)6}]·2H2O (en = 1,2-diaminoethane) (1) and [Zn(pn){B6O7(OH)6}]·1.5H2O (pn = 1,2-diaminopropane) (2), are reported. These complexes crystallize from aqueous solutions containing 10:1 ratios of B(OH)3 and the appropriate Zn(II) amine complexes ([Zn(en)3][OH]2 or [Zn(pn)3][OH]2) through self-assembly processes. The hexaborate(2−) anions in 1 and 2 are coordinated to two Zn(II) centers and form one-dimensional (1-D) polymeric coordination chains. R22(8) and R22(6) inter-chain H-bond interactions play an important role in these self-assembly processes and are discussed.
Highlights
Anionic boron species are commonly referred to as borates
Polyborates are readily synthesized from the addition of B(OH)3 to a basic aqueous solution containing templating cations or by solvothermal methods [1]
Compounds are formed through self-assembly processes involving a dynamic combinatorial library (DCL) [2,3] of polyborate anions that are present in the aqueous reactant solution
Summary
Anionic boron species are commonly referred to as borates. Hydroxyoxidopolyborates (“oxidoborates” or “borates”) are a class of anionic boron derivatives that contain boron atoms bound only to hydroxyl oxygen atoms, or oxygen atoms that bridge boron centers. Polyborates are readily synthesized from the addition of B(OH) to a basic aqueous solution containing templating cations or by solvothermal methods [1]. Crystals 2018, 8, 470 encourage the formation of new polyborate anions, we recently adopted a strategy of using more highly charged (> +1) inert transition-metal complexes [13] as templating cations. Anions, we recently adopted a strategy of donor using more highly with charged (>+1) inert transition-metal. This strategy successful and we recently reported two novel isolated polyborate anions: complexes [13]was as templating cations. This strategy was successful and we recently. Atoms dodececaborate(6 in monodentate and modes [16]
