摘要

Pale yellow crystals of the compound [C4H10NO](2)[SeOCl4] (1) were isolated by adding morpholine to a saturated solution of SeCl4 in 98% ethanol (space group Pnma, a = 7.731(5) Angstrom, b = 21.053(16) Angstrom, c = 9.725(8) Angstrom at 150 K). The square pyramidal [SeOCl4](2-) anion in this morpholinium salt is a partial hydrolysis product of chloroselenates(IV). The anions are connected to chains by weak Se ... Cl interactions. The morpholinium cations form hydrogen bonds to Cl atoms of the anions. The red compound [C4H10NO](2)[SeBr10] (2) was synthesised by adding morpholine to a saturated solution of SeBr4 in 47% hydrobromic acid (space group P2(1)/c, a = 8.357(2) Angstrom, b = 17.656(6) Angstrom, c = 8.495(2) Angstrom, beta = 95.49(2)degrees at 150 K). The [Se2Br10](2-) anions consist of two edge sharing distorted octahedra. Intermolecular interaction connect the anions to a two-dimensional network. [References: 35]

Cl相互作用连接到链上。吗啉阳离子与阴离子的Cl原子形成氢键。通过将吗啉加到SeBr4在47%氢溴酸中的饱和溶液(空间群P2(1)/ c,a = 8.357(2)埃,b)中合成红色化合物[C4H10NO](2)[SeBr10](2) = 17.656(6)埃,c = 8.495(2)埃,β= 150 K时95.49(2)度。 [Se2Br10](2-)阴离子由两个边缘共享的扭曲八面体组成。分子间的相互作用将阴离子连接到二维网络。 [参考:35]
