The electron-precise binary boron subhalide species [B X ] X=F, Br, I) were synthesized and their structures confirmed by X-ray crystallography. The existence of the previously claimed [B Cl ] , which had been questioned, was also confirmed by X-ray crystallography. The dianions are isoelectronic to hexahaloethanes, are subhalide analogues of the well-known tetrahaloborate anions (BX ), and are rare examples of molecular electron-precise binary boron species beyond B X , BX , and [BX ] .
电子精确的二元硼亚卤化物物种[BX]（X = F、Br、I）被合成出来，并且它们的结构通过X射线晶体学得以证实。之前所声称的一直受到质疑的[BCl]的存在，也通过X射线晶体学得到了证实。这些二价阴离子与六卤乙烷是等电子体，是著名的四卤硼酸根阴离子（BX₄⁻）的亚卤化物类似物，并且是除了BX₃、BX₅和[BX₆]²⁻之外分子电子精确的二元硼物种的罕见例子。
