| Abstract: | C6H12N4Br4Ag4,Mr = 891.31, orthorhombic, Pnma, a = 8.778(2),b = 9.80.5(2), c = 16.906(3) A, V = 1455.1(4) A3, Z = 4, Dx = 4.069, Dm (displacement of H2O) = 4.03 g cm-3 , A(Mo-Ka) = 161.3 cm-1 , F(OOO) = 1615.77,T = 295°, final R = 0.052 arid Rw = 0.062 for 1472 observed reflections.All four lone pairs of each (CH2)6N4 molecule serve as ligand sites in a polymeric framework comprising octahedral AgBr5N, tetrahedral AgBr3N, and tetragonal pyramidal AgBr4N coordination polyhedra. The Ag-N and Ag-Br bond lengths lie in the ranges 2.366(12)-2.454(12) and 2.640(2)-3.178(2) A, respectively. |
