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.

s-Block metal scorpionates – 一种新的氢化三（3,5-二甲基-1-吡唑基）硼酸钠盐，显示出通过桥接和末端 O 键合 DMSO 配体稳定的不寻常核心

摘要 [(μ-Me2CO)3(NaTp*)2] (1) (Tp* = hydrido-tris(3,5-dimethyl-1-pyrazolyl)borate) 在室温下溶解在 DMSO 中导致无色晶体表征为新盐 [Na2Tp*(μ-Me2SO)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(10) Å，c = 33.9685(2) Å，V = 5867.35(17) Å3。有趣的是，2 的阴离子和阳离子都包含 Tp* 配体。此外，阳离子部分突出了一个不寻常的钠原子，由六个作为 O 键配体的 DMSO 分子六配位。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。
