First claim
Opening claim text (preview).
What is claimed is: 1. A gas detection material comprising a Hofmann type porous coordination polymer of {Fe(pz)[Ni(CN) 4 ]} which contains ferrous ion, tetracyanonickelate ion and pyrazine as the essential ingredients and has a pillared crystal shape, wherein, pz=pyrazine. 2. The gas detection material according to claim 1 , wherein a part or the whole of the gas detection material is in low-spin state. 3. The gas detection material according to claim 2 , wherein the gas detection material contains acetonitrile. 4. The gas detection material according to claim 1 , wherein the gas detection material contains acetonitrile. 5. A lithium ion secondary battery, wherein, the outer package of the lithium ion secondary battery comprises the gas detection material of claim 1 . 6. The gas detection material according to claim 1 , wherein the pillared crystal shape has a size in a long axis direction of about 3 to 15 μm. 7. The gas detection material according to claim 6 , wherein the size is about 5 to 15 μm. 8. A gas detection tape made by laminating a gas detection material on at least one surface of the supporter, wherein, the gas detection material contains a Hofmann type porous coordination polymer of {Fe(pz)[Ni(CN) 4 ]} which contains ferrous ion, tetracyanonickelate ion and pyrazine as the essential ingredients and has a pillared crystal shape, wherein, pz=pyrazine. 9. A lithium ion secondary battery, wherein, the outer package of the lithium ion secondary battery comprises the gas detection tape of claim 8 .
