The synthesis and single-crystal structures of four alkali+ metal amalgams are reported. The compounds A 3 Hg 20 (A β«Ψβ¬ Rb, Cs) are of new structural type (Pm-3n, Zβ«,2Ψβ¬ a β«Ψβ¬ 10.737(1) A s and 10.913(1) A s , for A β«Ψβ¬ Rb and Cs, respectively), while K 3 Hg 11 is the 5rst example of a mercury compo
Blue crystals of metal nitratocuprates(II), M 3 [Cu(NO 3 ) 4 ](NO 3 ) (M = K (I), NH 4 (II), Rb (III)) and Cs 2 [Cu(NO 3 ) 4 ] (IV) were synthesized from Cu(NO 3 ) 2 3 H 2 O and MNO 3 by heating at 100Β±140 Β°C during 3Β±12 h. X-ray single crystal structures for isotypic I and II reveal the presence of
