Jarosewichite and a related phase: basic manganese arsenates of the chlorophoenicite group from Franklin, New Jersey

Jarosewichite, Mn3+Mn3+(AsOn)(OH)0, is a new mineral, closely related to chlorophoenicite, from the Franklin mine, Franklin, Sussex County, New Jersey, where it occurs associated with andradite, franklinite, flinkite, cahnite and hausmannite. Jarosewichite is orthorhombic, space grotp C2lmLlm2lm, C222 or Cmm2, with a : 6.56(3), b : 25.20(10), c : 10.00(5)4, and Z : 8. The strongest lines in the...

Synthesis and characterization of four ethylenediamine-templated iron arsenates.

Four new ethylenediamine-templated iron arsenates and fluoroarsenates have been hydrothermally synthesized from iron metal, hydrofluoric and arsenic acids, and ethylenediamine. Fe(H2AsO4)(HAsO4)2.enH2.H2O (1) is one-dimensional and contains chains, FeIIIFeIIF2(HAsO4)(AsO4).enH2.2H2O (2) is a layered fluoroarsenate, and Fe3(HAsO4)6.enH2.NH3.NH4 (3) and Fe2F2(AsO4)2(H2O).enH2 (4) are an arsenate ...

Can arsenates replace phosphates in natural biochemical processes? A computational study.

A bacterial strain, GFAJ-1 was recently proposed to be substituting arsenic for phosphorus to sustain its growth. We have performed theoretical calculations for analyzing this controversial hypothesis by examining the addition of phosphate to ribose and glucose. Dispersion corrected Density Functional Theory (DFT) calculations in small molecules and QM/MM calculations on clusters derived from c...
