摘要

本文描述了以前未报道过的化合物TiSe3在6gpa压力下的固态合成、晶体结构和基本电子性质。晶体结构是基于相互耦合的Ti-Se三角形棱镜的一维链，其中Se - Se对中包含三分之二的Se，与TiS3相似。与三硫化物不同的是，三硫化物只能在800至900°C的压力下生成。这种材料是半导体和弱抗磁性的。

Synthesis, Crystal Structure, and Elementary Electrical Characterization of Quasi-One-Dimensional TiSe3

The solid-state synthesis at an applied pressure of 6 GPa, crystal structure, and elementary electronic properties of the previously unreported compound TiSe₃ are described. The crystal structure, which is based on 1D chains of Ti–Se triangular prisms that are coupled to each other, with two-thirds of the Se involved in a Se–Se pair, is similar to that of TiS₃. Unlike the trisulfide, the triselenide is only made under pressure at temperatures between 800 and 900 °C. The material is semiconducting and weakly diamagnetic.

期刊介绍： Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
