Abstract
a zero-dimensional metal tin mixed halide compound exhibiting color change due to crystal water loss. Abstract A new zero-dimensional alkali-metal tin mixed halide, K 6 Sn 4 F 12 I 2 • 0.5H 2 O, is synthesized by a hydrothermal method. It crystallizes in the cubic centrosymmetric space group of Fd-3m (No. 227) and its structure consists of crystal water molecules and ordered arranged [Sn 4 F 12 I 4 ] fundamental structural blocks trapped in [K 18 ] cages. Interestingly, K 6 Sn 4 F 12 I 2 • 0.5H 2 O exhibits a color change from colorless to orange when exposed to air. Experimental measurements combined with theoretical calculations reveal that the color change in K 6 Sn 4 F 12 I 2 • 0.5H 2 O is attributed to the loss of crystal water.
一种零维金属锡混合卤化物化合物，由于结晶水的损失而表现出颜色变化。摘要:采用水热法合成了一种新的零维碱金属锡混合卤化物k6sn 4f12i2•0.5 h2o。它在Fd-3m(227号)的立方中心对称空间群中结晶，其结构由结晶水分子和被囚禁在[K 18]笼中的有序排列的[Sn 4 F 12 I 4]基本结构块组成。有趣的是，k6 Sn 4 f12 I 2•0.5 h2o暴露在空气中，呈现出从无色到橙色的变化。实验测量与理论计算相结合表明，k6sn4f12i2•0.5 h2o的颜色变化是由于结晶水的损失造成的。
期刊介绍：
Micro and Nanostructures is a journal disseminating the science and technology of micro-structures and nano-structures in materials and their devices, including individual and collective use of semiconductors, metals and insulators for the exploitation of their unique properties. The journal hosts papers dealing with fundamental and applied experimental research as well as theoretical studies. Fields of interest, including emerging ones, cover:
• Novel micro and nanostructures
• Nanomaterials (nanowires, nanodots, 2D materials ) and devices
• Synthetic heterostructures
• Plasmonics
• Micro and nano-defects in materials (semiconductor, metal and insulators)
• Surfaces and interfaces of thin films
In addition to Research Papers, the journal aims at publishing Topical Reviews providing insights into rapidly evolving or more mature fields. Written by leading researchers in their respective fields, those articles are commissioned by the Editorial Board.
