Title Thermoelectric conversion element
Abstract Provided is an easy-to-process thermoelectric conversion element the shape of which can be freely changed. The element has electrodes and an ionic solid wherein the ionic solid comprises an anionic heterometal complex and a cationic species. The anionic heterometal complex comprises a metal M1 selected from groups 8, 9, and 10 of the Periodic Table or Cr, or Mn; a metal M2 selected from group 11 or group 12 of the Periodic Table; and a ligand. The anionic heterometal complex forms a crystal lattice by aggregation, and the cationic species is present in the interstices of the crystal lattice.
Scope of claims [claim1]
1. An element comprising an ionic solid and an electrode, wherein the ionic solid is formed by aggregating anionic dissimilar metal complexes each comprising 1 metal M1 selected from the group consisting of the group 8, the group 9, the group 10, Cr and Mn of the periodic Table, 1 metal M2 selected from the group 11 and the group 12 of the periodic Table and a ligand, and a cationic species is present in the gaps in the lattice.

[claim2]
2. The element according to claim 1, wherein the metal M1 of group 8, group 9 or group 10 of the periodic table is 1 selected from Fe, Ru, Os, Ru, Rh, Co, Pd, Os, Ir and Pt.

[claim3]
3. The element of claim 1 or 2, wherein the metal M2 is Zn, Cd, Hg, Au, Ag or Cu.

[claim4]
4. The element according to any one of claims 1 to 3, wherein the ionic solid is an ionic solid represented by general formula (1),
(X)l〔(M1)4(M2)4(Am)12(E)m〕·nH2O……(1)
wherein M1 represents Fe, Ru, Os, Rh, Pd, Co, Ir, Pt, Cr or Mn;
m2 represents Zn, Cd, Hg, Au, Ag or Cu;
x represents a cation;

e represents O2-、S2-、Se2-、Te2-、F-、Cl-、Br-、I-Or H-;
l represents a number of 4 to 14 in terms of the product of the ionic valence of X;
m represents a number of 0 or 1;
n represents a number of 1 to 100.

[claim5]
5. The element according to claim 4, wherein the anionic dissimilar metal complex in the general formula (1) is a complex represented by a general formula (2),
〔(M1)4(M2)4(Am)12(E)m〕l-……(2)
wherein M1 represents Fe, Ru, Os, Rh, Pd, Ir, Pt, Cr or Mn;
m2 represents Zn, Cd, Hg, Ag or Cu;
am represents an amino acid;
e represents O2-、S2-、Se2-、Te2-、F-、Cl-、Br、I-Or H-;
l represents a number of 4 to 14 in terms of the product of the ion valence of X in the formula (1);
m represents a number of 0 or 1.

[claim6]
6. The element according to claim 4 or 5, wherein Am is an amino acid having a thiol group.

[claim7]
7. The element according to any one of claims 4 to 6, wherein X is a cation of a metal belonging to group 1 or group 2.

[claim8]
8. The element according to any one of claims 4 to 7, wherein M1 represents Rh or Co, and M2 represents Ag or Zn.

[claim9]
9. The element according to any one of claims 4 to 8, wherein Am is an amino acid selected from cysteine, penicillamine and homocysteine.

[claim10]
10. An element according to any one of claims 1 to 9 which is an electrical heating element.

[claim11]
11. The element according to any one of claims 1 to 10, wherein the element generates a temperature distribution in the ionic solid by applying a potential difference to the element, thereby generating a concentration gradient of mobile ions in the ionic solid.

[claim12]
12. The element according to any one of claims 1 to 10, wherein the element is varied by applying heat to the element to generate a concentration gradient of mobile ions in the ionic solid, thereby generating a potential difference in the ionic solid.

[claim13]
13. A method of passing an electric current through the element as claimed in any one of claims 1 to 10 to generate a concentration gradient in the ionic solid of the element and heat in the ionic solid of the element.
