magnesium fluorooxoborate MgB5O7F3 was synthesized as a new competitive candidate for deep-ultraviolet nonlinearopticalapplication. It has a sufficiently large nonlinearity and a deep-ultraviolet phase matching wavelength, indicating that it holds great potential for the production of coherent light below 200 nm. The critical performance enhancement of MgB5O7F3 when compared with its isomorphic phases
通过利用非线性光学晶体和简单的倍频过程,可以调谐产生的光以覆盖从深紫外到太赫兹波长的几乎整个光谱范围。其中,发现产生深紫外光的新候选物是实现巨大潜力的巨大挑战。实际上,该工艺的可用性主要取决于关键性能是否可以很好地共存于一个实用的晶体中。在此,第一氟硼酸镁MgB 5 O 7 F 3被合成为深紫外非线性光学应用的新竞争候选者。它具有足够大的非线性和深紫外相位匹配波长,表明它具有产生 200 nm 以下相干光的巨大潜力。证明并讨论了 MgB 5 O 7 F 3与其同晶相相比的关键性能增强。更重要的是,我们提出通式为MB 5 O 7 F 3 (M=二价金属)的氟氧硼酸盐体系具有稳定的氟封端骨架,这使得它们倾向于保持其结晶空间群不变。
The chemoselective electrochemical cleavage of allyl aryl ethers catalyzed by Ni(bipy)(3)(2+)2BF(4)(-) was shown to proceed through electrogenerated Ni(0) complexes with the formation of pi-allyl Ni(II) species, which are in turn reduced at the same potential as the initial Ni(II)/Ni(0) reduction. The important role of magnesium ions in the recycling of the nickel species was established.

Ca, Sn, Pb) with 2,6-lutidineN-oxide (L) at ambient temperature results in the precipitation of ML4(BF4)2 (M = Mg, Ca) or MLF(BF4) (M = Sn, Pb). The new Mg2+ and Ca2+ adducts appear to be pentacoordinated of the [ML4(FBF3)](BF4) type, involving both ionic and coordinated BF4 groups. The Sn2+ and Pb2+ complexes are presumably produced by elimination of one molecule of the BF3L complex from the initially
