چکیده
The Cd atom in the hydrated title salt, (C(7)H(11)N(2))(2)[CdBr(4)]·H(2)O, exists in an approximately tetra-hedral coordination geometry, with Br-Cd-Br angles in the range 105.52 (3)-111.50 (3)°. The cation, anion and water mol-ecule inter-act by O-H⋯Br, N-H⋯Br and N-H⋯O hydrogen bonds, forming a linear chain structure running along the a axis.

In the crystal structure of the title compound, (C7H11N2)2[Mn(NCS)4(C7H10N2)2], the manganese(II) cations are coordinated by four N-bonded thio-cyanate anions and two N-bonded 4-(dimethyl-amino)-pyridine ligands into discrete complex dianions. For charge balance, two 4-(dimethylamino)pyridine counter cations are present, which do not coordinate to the metal cation. The asymmetric unit consists ...
