摘要：

The silver cyanoguanidine complexes [Ag(cgn)(2)]F (1), [Ag(cgn)(2)][BF4] (2), [Ag(cgn)(2)][ClO4] (3) and [Ag(cgn)][NO3] (4) were obtained from aqueous solutions of the corresponding silver salts and cyanoguanidine. The crystal structures of 1 and 2 have been determined by single crystal X-ray diffraction. 1: Space group P (1) over bar, Z = 2, cell constants at -65 degreesC: a = 618.18(3), b = 761.49(8), c = 971.2(1) pm; alpha = 93.56(1), beta = 97.439(8), gamma = 97.376(9)degrees; R-1 = 0.0218. 2: Space group P (1) over bar, Z = 2, cell constants at -65 degreesC: a = 549.79(9), b = 958.17(17), c = 1121.04(12) pm; alpha = 90.026(13), beta = 102.520(11), gamma = 95.937(14)degrees; R-1 = 0.0283.
