with a 0.8945(1), b 1.2355(2), c 1.3572(5) nm, a 98.69(2), b 92.74(2), and g 90.45(1)? Z = 2. All 3 Ag atoms have the same coordination no. 5, but their coordination polyhedra are different. The tetragonal pyramid and trigonal bipyramid are formed for Ag(3) and Ag(2) resp. and the coordination polyhedron of Ag(1) is between them. The coordination of NO3- with Ag may be divided into 2 classes, in 1 of them NO3- is bonded to Ag with unidentate and bidentate having unequal bond length and in other with bidentate having equal bond length. The ligand coordinates with Ag also with 2 conformation. The chair conformation has Ci symmetry and its coordination with Ag is again in 2 forms. The gauche conformation has no Ci symmetry and coordinates with Ag to form a 5-membered chelate ring. The complex is a large mol. having 3-dimensional unlimited chains. Atomic coordinates are given.
