Abstract
Crystals of LiCs2[N(CN)2]3 were obtained from the reaction of stoichiometric amounts of aqueous solutions of LiCl and CsBr with Ag[N(CN)2]. X-ray single-crystal structure analysis showed that LiCs2[N(CN)2]3 crystallizes isotypically to NaCs2[N(CN)2]3 and adopts the hexagonal space group P63/m (No. 176), with a = 6.8480(8), c = 14.1665(17) Å, and Z = 2. The IR and Raman spectra of the title compound exhibit modes typical for the dicyanamide anion.
Highlights
Nitrogen-based materials are interesting for research purposes and for industrial applications
High-performance steel coatings, or lithium-ion battery materials [1,2], the research on nitrogen compounds has advanced and recently focused on complex nitrogen-containing compounds opposed to simple nitrides [3]
We here report the synthesis and single-crystal structure determination of the new pseudo-ternary compound LiCs2 [dca]3 according to its IR and Raman spectra
Summary
Nitrogen-based materials are interesting for research purposes and for industrial applications. One interesting inorganic moiety is the boomerang-shaped dicyanamide anion [N(CN)2 ]− which is often dubbed as [dca]−. Species has been found to allow for a rich diversity of compounds, due to its chemical stability as well as its ability to coordinate metal ions through terminal and/or bridging nitrogen atoms. Whenever coordination with all three nitrogen atoms of the [dca] anion occurs, ferromagnetic and antiferromagnetic transition-metal compounds with a rutile-like structure result [4]. [dca]− forms one-dimensional (1D)- and two-dimensional (2D)-structures, which makes this anion interesting for crystal engineering [5]. We here report the synthesis and single-crystal structure determination of the new pseudo-ternary compound LiCs2 [dca]3 according to its IR and Raman spectra
