Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Remarks:
Handbook data are considered from a trusted source. Data have been taken from many sources, including both compilations and the primary literature - where conflicts were found, the value deemed most reliable was chosen. The reference was peer-reviewed. In addition, the reference sources are indicated although not leading to sufficient information on the material & method used.

Description of key information

Combining three handbook results, magnesium nitrate could be described as colourless or white, cubic hygroscopic crystals (anhydrous form) or  colourless clear, deliquesc monclinic crystals (hexahydrate form).
