Saline (salt-like) hydrides
Group 1 metal hydrides are white crystalline solids; each contains the metal ion and a hydride ion, H-. They have the same crystal structure as sodium chloride, which is why they are called saline or salt-like hydrides. Because they can react violently with water or moist air, they are normally supplied as suspensions in mineral oil.
