Abstract

Single crystals of the new compound (H 2dabco)[Cu(H2O)6][Cu(SeO4)2(H2O)4]2 are prepared in good yield (not given) from aqueous solutions of CuCO3·2Cu(OH)2, DABCO, and H2SeO4 in the molar ratio of 1:1:2 at room temperature. The compound crystallizes in the monoclinic space group P2 1/n with Z = 2 (single crystal XRD). The structure contains [Cu(SeO 4)2(H2O)4] 2anions, slightly distorted octahedral [Cu II (H2O)6] groups, and disordered [H2dabco] 2+ cations linked by hydrogen bonds. -(REKIK, W.; LOULOU NKHILI, N.; NAILI*, H.; DAHAOUI, S.; Z.
