Isotopic Tracing of Perchlorate Sources in the Environment
Journal of Chemistry, 2021 Perchlorate (ClO4−) is an emerging persistent pollutant that is ubiquitous in the environment at trace concentrations. Perchlorate ingestion poses a risk to human health because it interferes with thyroidal hormone production.

Acta Crystallographica Section E Structure Reports Online, 2011 IN THE TITLE SALT (SYSTEMATIC NAME: 6-amino-9H-purin-1-ium perchlorate), C(5)H(6)N(5) (+)·ClO(4) (-), the adeninium cation is essentially planar, with a maximum deviation of 0.038 (1) Å. The whole of the perchlorate anion is disordered over two sets of sites with an occupancy ratio of 0.589 (13):0.411 (13).

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.
