Abstract

A halide includes a crystal having a composition represented by ASn 2 X 5 . In the composition, A is a molecular cation containing at least one nitrogen atom and X is a halogen element.

First claim

What is claimed is:

1 . A halide comprising:
a crystal having a composition represented by ASn 2 X 5 , where A is a molecular cation containing at least one nitrogen atom, and X is a halogen element.

2 . The halide according to claim 1 , wherein the molecular cation further contains at least one carbon atom.

3 . The halide according to claim 1 , wherein the molecular cation is an ammonium ion represented by the following formula:

where R 1 , R 2 , R 3 , and R 4 are each independently a hydrogen atom, an alkyl group, an aryl group, or NH 2 .

4 . The halide according to claim 3 , wherein in the formula, R 1 and R 2 are each independently a hydrogen atom, an alkyl group, or an aryl group, and R 3 and R 4 are each a hydrogen atom.

5 . The halide according to claim 4 , wherein in the formula, R 1 , R 2 , R 3 , and R 4 are each a hydrogen atom.

6 . The halide according to claim 3 , wherein in the formula, R 1 is NH 2 and R 2 , R 3 , and R 4 are each a hydrogen atom.

7 . The halide according to claim 1 , wherein the halide has an anti-perovskite structure.

8 . The halide according to claim 1 , wherein the halide has a relative dielectric constant of higher than 52 at 1 MHz.

9 . A dielectric material comprising the halide according to claim 1 .

10 . A capacitor comprising:
a first electrode; a second electrode; and a dielectric disposed between the first electrode and the second electrode, wherein the dielectric comprises the halide according to claim 1 .

11 . An electric circuit comprising the capacitor according to claim 10 .

12 . A circuit board comprising the capacitor according to claim 10 .

13 . A device comprising the capacitor according to claim 10 .
