摘要
InF3 (H2O) 2是一种新型的单斜C2 / m期(a = 5.774 (2), b = 10.239 (3) a, c = 4.1150(8),β= 118.16(2)°)。在密封管中合成InF3-TeO2体系的相时，偶然得到了很少的单晶。也可以通过将InF3或In2O3直接溶解在40%的HF中，然后在50-70℃左右缓慢蒸发来制备。InF3(H2O)2结构是由InF4(OH2)2八面体的反式链[InF3(H2O)2]n组成的，它们共用F顶点，通过相邻链的赤道O/F之间的强OH··F氢键连接，相邻链的O··F键短为2.57 Å和2.60 Å。提出了一个介于F(1)和O(1)赤道阴离子之间的中阶。InF3(H2O)2似乎是三价金属氟化物的第一个简单二水合物。将其与InF3(H2O)3和其他具有类似结构特征的三水合物进行了比较。
InF3(H2O)2 : An indium fluoride dihydrate phase with direct O-H...F hydrogen bonding between isolated columns of InF4(OH2)2 corner-sharing octahedra
InF3(H2O)2 is a new monoclinic C2/m phase [a = 5.774(2) Å, b = 10.239(3) Å, c = 4.1150(8) Å, β = 118.16(2)°]. It is obtained fortuitously as very few single crystals during the synthesis in sealed tubes of the phases in the system InF3-TeO2. It can also be prepared by direct dissolution of InF3 or In2O3 in HF 40 %, followed by a slow evaporation of the solution about 50–70 °C. It corresponds to an intermediate unstable dihydrate in the process of hydration of InF3 at air to a stable trihydrate InF3(H2O)3.
InF3(H2O)2 structure is composed of trans-chains [InF3(H2O)2]n of InF4(OH2)2 octahedra sharing F vertices, interconnected via strong OH···F hydrogen bonds between equatorial O/F of adjacent chains with short O···F bonds of 2.57 Å and 2.60 Å. A medium range order between F(1) and O(1) equatorial anions is proposed. InF3(H2O)2 seems to be the first simple dihydrate of trivalent metal fluorides. It is compared to InF3(H2O)3 and to other trihydrates presenting some similar structural features.
期刊介绍：
The Journal of Fluorine Chemistry contains reviews, original papers and short communications. The journal covers all aspects of pure and applied research on the chemistry as well as on the applications of fluorine, and of compounds or materials where fluorine exercises significant effects. This can include all chemistry research areas (inorganic, organic, organometallic, macromolecular and physical chemistry) but also includes papers on biological/biochemical related aspects of Fluorine chemistry as well as medicinal, agrochemical and pharmacological research. The Journal of Fluorine Chemistry also publishes environmental and industrial papers dealing with aspects of Fluorine chemistry on energy and material sciences. Preparative and physico-chemical investigations as well as theoretical, structural and mechanistic aspects are covered. The Journal, however, does not accept work of purely routine nature.
For reviews and special issues on particular topics of fluorine chemistry or from selected symposia, please contact the Regional Editors for further details.
