Morpholinium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2008 In the title salt, C(4)H(10)NO(+)·ClO(4) (-), which has three independent formula units, the cations are linked into chains along [100] by N-H⋯O hydrogen bonds. Each cation acts both as a donor and as an acceptor, and every cation makes one N-H⋯O hydrogen bond with a ClO(4) (-) anion. The crystal studied was an inversion twin.

Acta Crystallographica Section E Structure Reports Online, 2009 The title compound, C4H8N3O+·ClO4−, is built up from creatininium cations and perchlorate anions. Crystal cohesion and perchlorate stability are ensured by N—H⋯O hydrogen bonds that together with weak C—H⋯O interactions build up a three-dimensional network.

Heats of formation of lithium perchlorate, ammonium perchlorate, and sodium perchlorate
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961 Calorimetric measurements of the heats of solution of LiClO4(c), NH4ClO4(e), and NaClO4(c) have been made. The results have been combined with the heats of formation of KClO4(c), KCl(c), LiCl(c), NH4Cl(c), and NaCl(c), to obtain the following heats of formation: LiClO 4 ( c ) , Δ Hf ° ( 25 ° C ) = - 380.27 ± 1.21 kj / mole = - 90.89 ± 0.29 ...
