The physical properties of this chemical are below: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 157.924101; (6)MonoIsotopic Mass: 157.924101; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1.

When you are using this chemical, you should be very cautious. For one thing, it is irritant which may cause inflammation to the skin or other mucous membranes. This chemical is irritating to eyes and skin. For another thing, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water. If contacting with water, it liberates extremely flammable gases.

Therefore, you could take the different measures to deal with different cases. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice; If in case of fire use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water); When you are storing, keep the container tightly closed and dry.

Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [Gd]
(2)InChI: InChI=1S/Gd
(3)InChIKey: UIWYJDYFSGRHKR-UHFFFAOYSA-N
