Ammonium imidazolium dichromate
In the crystal structure of the title compound, (C(3)H(5)N(2))(NH(4))[Cr(2)O(7)], the anions and cations are linked through N-H⋯O hydrogen bonds, resulting in a three-dimensional structure which contains three kinds of layers parallel to (001). One layer contains imidazole cations, the other two layers the ammonium cations and dichromate anions. The dichromate anion has an eclipsed conformation...
متن کاملBis(benzyltrimethylammonium) dichromate(VI)
The asymmetric part of the title compound, (C(10)H(16)N)(2)[Cr(2)O(7)], contains one cation and a half of the dichromate dianion, which has a staggered conformation and exhibits disorder of the bridging O atom around the inversion center over two positions in a 1:1 ratio. Weak inter-molecular C-H⋯O hydrogen bonds link cations and anions into a three-dimensional structure.
متن کاملComparison of dichromate and ethanol-chlorobenzene dosimeters in high dose radiation processing
Radiation processing in many areas, particularly in radiation sterilization, demands control of the absorbed dose. Many dosimeters have been proposed for the high-level dose range (region of 10 to 50 kGy). However, in addition to the required reproducibility, reliability or uncertainty (< 5%), it is desirable for radiation processing that the selected dosimetric system is easy to operate. One o...
متن کاملBis(4-aminopyridinium) dichromate(VI)
The asymmetric unit of the title salt, (C5H7N2)2[Cr2O7], contains four independent cations and two independent dichromate anions. The crystal structure consists of discrete dichromate anions with an eclipsed conformation stacked in layers parallel to (010) at y = 1/4 and y = 3/4. These layers are linked via 4-amino-pyridinium cations by N-H⋯O and weak C-H⋯O hydrogen bonds, forming a three-dimen...
متن کاملPropane-1,3-diammonium dichromate(VI)
The title compound, (C(3)H(12)N(2))[Cr(2)O(7)], consists of a discrete dichromate anion with an eclipsed conformation and a propane-1,3-diammonium cation. Both kinds of ions have a mirror plane passing through the bridging O atom and the central methyl-ene C atom of the Cr(2)O(7) (2-) and C(3)H(12)N(2) (2+) moieties, respectively. Anions and cations are alternately stacked to form columns paral...
