摘要

摘要室温下，[（μ-Me2CO）3（NaTp*）2]（1）（Tp*=三（3,5-二甲基-1-吡唑基）硼酸氢酯）在二甲基亚砜中的溶解导致无色晶体的生长，其特征为新的盐[Na2Tp*（μ-Ma2SO）3（Me2SO）3][NaTp*2]（2）。2在三角空间群R3中结晶，Z＝3，a＝14.1227（2）Å，b＝14.1227，c＝33.9685（2）å，V＝5867.35（17）Å3。有趣的是，2的阴离子和阳离子都含有Tp*配体。此外，阳离子部分突出了一个由六个DMSO分子作为O-键合配体六配位的不同寻常的钠原子。其中三个表现出桥接协调模式，三个处于终端位置。据我们所知，[Na2Tp*（μ-Me2SO）3（Me2SO）3]的框架是前所未有的。

s-Block metal scorpionates – A new sodium hydrido-tris(3,5-dimethyl-1-pyrazolyl)borate salt showing an unusual core stabilized by bridging and terminal O-bonded DMSO ligands

Abstract Dissolution of [(μ-Me2CO)3(NaTp*)2] (1) (Tp* = hydrido-tris(3,5-dimethyl-1-pyrazolyl)borate) in DMSO at room temperature leads to the growth of colourless crystals characterized as the new salt [Na2Tp*(μ-Me2SO)3(Me2SO)3] [NaTp*2] (2). 2 crystallized in the trigonal space group R3 with Z = 3, a = 14.1227(2) Å, b = 14.1227(10) Å, c = 33.9685(2) Å, and V = 5867.35(17) Å3. Interestingly, anion and cation of 2 both contain the Tp* ligand. Moreover, the cationic moiety highlights an unusual sodium atom hexacoordinated by six DMSO molecules acting as O-bonded ligands. Three of which exhibit a bridging coordination mode and three are in terminal position. To the best of our knowledge, the framework of [Na2Tp*(μ-Me2SO)3(Me2SO)3] is unprecedented.
