โœฆ Synopsis


Guanidinium hydrogen selenate, CH 7 N 3 O 4 Se or [C(NH 2 ) 3 ] + ร-(HSeO 4 ) ร€ , is isotypic with its sulfate analogue. The atomic arrangement is characterized by hydrogen selenate tetrahedra and trigonal guanidinium groups, which are connected to each other by a network of mostly weak hydrogen bonds. All atoms are located on general positions.
