Tin ( II) iodide is an inorganic chemical compound of the tin from the group of iodides.
Production and representation
Tin ( II) iodide may be obtained by reaction of tin with iodine at higher than 600 ° C, wherein until tin (IV ) iodide forms, which reacts with excess tin to tin ( II) iodide.
It can also be represented by the reaction of a tin (II ) chloride solution with potassium iodide.
Properties
Tin ( II) iodide is a yellow to a red solid which is slightly soluble in water. It has a monoclinic crystal structure with space group C2 / m (a = 1417 pm, b = 453.5 pm, c = 1087 pm, 92 °, Z = 6). With halides it forms halogen complexes.
