The First Organically Templated Linear Metal Selenate

An organically templated cadmium selenate of the formula [enH2][Cd(H2O) 2(SeO4)2], I, has been synthesized by carrying out the reaction between CdO and H2SeO4 in the presence of the amine in aqueous medium at 80°C. the structure of I involves isolated infinite [Cd(H2O) 2 (SeO4)2]2- chains running along the c-axis, with the protonated ethylenediamine molecules between them. Crystal data for I are as follows: Monoclinic, space group=C2/c, a=10.5059(7), b=10.3605(7), c=10.6028(7) Å, ß=94.666(2)°, V = 11.50.25(13) Å3, z=8, R1=0.0237, wR2=0.0500 (for all data)
