Abstract
The preparation and X-ray structure of [Ag(9-EtGH-N7)2]NO3.H2O (9-EtGH = neutral 9-ethylguanine) is reported. The compound crystallizes in t he triclinic system, space group P1BAR with a = 7.063(6), b = 7.153(3) , c = 11.306(10) angstrom, alpha = 83.36(6), beta = 76.66(7), gamma = 81.44(6)-degrees The cation is centrosymmetric with Ag(I) coordinated via two N7 positions and Ag-N7 bond lengths of 2.11(1) angstrom. Apply ing Ag-109 NMR spectroscopy, complex formation constants for both the 1:1 complex (log beta1 = 0.6) and the title compound (log beta2 = 1.6) in Me2SO have been determined.
