The influence of the cations on the condensation of anions CdBr 4 2 ~ in salts (A')CdBr4(II) and (A) 2 CdBr 4 ( I I ) is studied by 79 ,81 Br N Q R and X-ray crystal structure determinations. (A')CdBr4 : A' = [H 3 N(CH 2 ) 3 NH 3 J 2 + (1) crystallizes with a layer-type anion structure at 298 K and A' = [ l ,4 (H 3 N) 2 C 6 H 4 J + (2 ) crystallizes with a(More)
The Hg atoms in the crystal structure of the title compound, (CH(6)N(3))(2)[HgBr(4)], are tetra-hedrally coordinated by four Br atoms and the resulting [HgBr(4)](2-) tetra-hedral ions are linked to the [C(NH(2))(3)](+) ions by bromine-hydrogen bonds, forming a three-dimensional network. In the structure, the anions are located on special positions. The two(More)
The Hg atom in the crystal structure of the title compound, (CH(6)N(3))(2)[HgI(4)], is tetra-hedrally coordinated by four I atoms. The [HgI(4)](2-) ions are inter-connected to the [C(NH(2))(3)](+) ions by N-H⋯I hydrogen bonds, forming a three-dimensional network. The four different observed Hg-I distances [2.760 (2), 2.7762 (15), 2.8098 (14) and 2.833 (2)(More)
The structure of the condensed bromocadmate anions in [C(NH2)3]Cd2Br5 (1) and [H2NNH3]3CdBr5 (2) were studied at room temperature by X-ray diffraction. (1) crystallizes with double-chains bridged by Br atoms (orthorhombic, Pmmn, Z = 2, a = 1394.0(5), b = 394.5(1), c = 1086.9(5) pm). This chain structure was not described previously. (1) shows three 8 'Br(More)
8 Br and A1 NQR were observed in AlBr3 complexes with 4 -XC 6 H 4 NO,(X = H, CI, Br, I, C H 3 , and C 2 H 5 ) , C 6 H ? C O B r , (C 6 H 5 ) 2 CO, and ( C 2 H 5 ) 2 0 . In the 4 -XC 6 H 4 NÖ 2 complexes, the A1 quadrupole coupling constants (QCC's) were well correlated with the Hammett erp's of the para-substituents, i.e., electron-withdrawing groups caused(More)

The coordination capability of Cl and Br in halogenocadmate(II) complexes is estimated by a solution of the structure of 1,3-propanediammonium dibromodichlorocadmate(II). The compound crystallizes as a layered anion structure with Cl bridges and Br terminals at 293 K: Imma, a = 741.56(7), b = 1869.5(5), and c 771.55(8) pm, Z = 4. In order to explain the(More)
