The present invention provides metal-organic materials, more specifically organometallic polymers, comprising polypyridyl organic ligands such as tetrakis(4-(pyridin-4-ylethynyl)phenyl)methane, tetrakis(4-(2-(pyridin-4-yl)vinyl)phenyl)methane,,3,5,7-tetrakis(4-(pyridin-4-ylethynyl)phenyl)adamantane or 1,3,5,7-tetrakis(4-(2-(pyridine-4-yl)vinyl)phenyl) adamantine, and metal ions structurally coordinated with said ligands, and having three-dimensional crystalline micro or sub-micro structure; as well as a method for the preparation thereof. These metal-organic materials are useful as adsorbents in processes for gas adsorption or separation. La présente invention concerne des matériaux organométalliques, plus spécifiquement des polymères organométalliques, comprenant des ligands organiques polypyridyle tels que le tétrakis(4-(pyridin-4-yléthynyl)phényl)méthane, le tétrakis(4-(2-(pyridin-4-yl)vinyl)phényl)méthane, le 3,5,7-tétrakis(4-(pyridin-4-yléthynyl)phényl)adamantane ou la 1,3,5,7-tétrakis(4-(2-(pyridine-4-yl)vinyl)phényl)adamantine, et des ions métalliques structurellement coordonnés auxdits ligands, et possédant une micro- ou sub-microstructure cristalline tridimensionnelle ; ainsi qu'un procédé pour leur préparation. Ces matériaux organométalliques sont utiles en tant qu'adsorbants dans des procédés d'adsorption ou de séparation de gaz.
