Structural Responses of Nucleic Acids to Mars-Relevant Salts at Deep Subsurface Conditions
Life, 2022 High pressure deep subsurface environments of Mars may harbor high concentrations of dissolved salts, such as perchlorates, yet we know little about how these salts influence the conditions for life, particularly in combination with high hydrostatic ...

Metronidazolium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 IN THE CRYSTAL STRUCTURE OF THE TITLE COMPOUND [SYSTEMATIC NAME: 1-(2-hy-droxy-eth-yl)-2-methyl-5-nitro-1H-imidazol-3-ium perchlorate], C(6)H(10)N(3)O(3) (+)·ClO(4) (-), the cations are linked by inter-molecular N-H⋯O hydrogen bonds into zigzag chains along the c axis. The cations and anions are connected by O-H⋯O and C-H⋯O hydrogen bonds. A weak intra-

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.

The Planetary Science Journal, 2023 Low water activity limits the habitability of aqueous environments, and salts present on Mars are known to reduce water activity. As environmental brines are not pure solutions of a single salt, predicting their water activity is difficult without direct
