✦ Synopsis
Acidic diphosphates are an important class of phosphates with many applications (Assaaoudi et al., 2002; Essehli et al., 2005, and references therein). The present paper deals with the synthesis and crystal structure of the Mg member of the series KM(HP 2 O 7 )Á2H 2 O, where M is a 3d divalent transition metal or Mg. KMg(HP 2 O 7 )Á2H 2 O is isotypic with the known
