摘要：

The title compound, [Ag(dppe)2]N03, is shown to be bis-chelated by two dppe ligands so that the silver atom is four-coordinate; Ag-P 2.488(3), 2 x 2.523(3) and 2.527(3) A. Distortions from ideal tetrahedral geometry are related to the restricted bite distances of the dppe ligands such that the P(1)-Ag-P(2) and P(3)-Ag-P(4) angles are 84.5(1) and 83.8(1)°, respectively. The compound crystallizes in the monoclinic space group P21/n with unit cell dimensions a = 14.834(2), b = 19.795(2), c = 15.856(3)A,β = 93.09(1)° and Z = 4. The structure was refined by a full-matrix least-squares procedure to final R = 0.063 for 3776 reflections with I 2.5 σ(7). © 1990, Taylor & Francis Group, LLC. All rights reserved.
