Nitrofurantoin (Macrodantin, Furadantin, Macrobid) is a drug available in three forms prescribed for the treatment or prevention of urinary tract infections (UTIs). Side effects, warnings and precautions, drug interactions, and patient information should be reviewed prior to taking any medication.
In this group the mineral is held together by the attraction between silica tetrahedra and other positive ions. Olivine and Garnet are examples of minerals within the independent tetrahedra group. Single chain silicates contain silica tetrahedra that are linked up in a chain by sharing two oxygen atoms. The most common single chain silicate is pyroxene. Double chain silicates form by sharing either two or three oxygen.
-isomorphism can exist with minerals which are not in the same mineral class--since they are not in the same mineral class they cannot be in the same isomorphic group--NaNO 3 (nitratite) is isomorphic or isostructural with the minerals in the calcite group of the carbonate class including siderite and calcite 2. polymorphic group is a mineral group belonging to the same mineral class, all having the
