“…The O-Ag-O angle is 180°, which is different from those (174.5(3)°and 178.0(1)°) in similar silver(I) complexes with aromatic carboxylates we reported [3,4]. The Ag-O bond length is 2.126(5) Å, which is slightly shorter than that in the similar complexes (2.146(5) Å [3] and 2.144(3) Å [4]). In the second molecule, the central metal atom is linearly two-ligated by two nitrogen atoms from two 4aminopyridine ligands.…”

“…The N-Ag-N locates in a line, which is also different from other similar complexes (ÐN-Ag-N = 173.47(8)° [1] and ÐN-Ag-N = 166.5(15)° [2]). The Ag-N bond length of 2.113(6) Å is comparable to those (2.114(2) Å and 2.118(2) Å) in the similar complex in [3]. The primary amine N atoms of the pyridine ligands, the water molecules and the uncoordinated O atoms of the carboxylic groups contribute to the formation of hydrogen bonds, which join the complexes to form a layered arrangement parallel to the bc plane.…”

C 24 H 24 Ag 2 N 6 O 10 , triclinic, P1 (no. 2), a = 3.807(3) Å, b = 11.55(1) Å, c = 16.21(1) Å, a = 74.17(1)°, b = 84.75(1)°, g = 89.89(1)°, V = 682.6 Å 3 , Z = 1, R gt (F) = 0.045, wR ref (F 2 ) = 0.153, T = 293 K. Source of materialAll reagents and solvents were used as purchased without further purification. C, H and N elemental analyses were performed on a Perkin-Elmer elemental analyzer. Ag 2O (1 mmol, 232 mg) and 3-nitrobenzoic acid (1 mmol, 151 mg) were dissolved in ammonia solution (10 ml), stirred for ca. 10 min to obtain a clear solution. 4-aminopyrimidine (1 mmol, 81 mg) was added to the above solution with stirring. After the solution was kept in air for four days with the ammonia gas escaping, large colorless crystals were formed, collected, washed with water, and dried in a vacuum desiccator using CaCl 2 (yield 55 %). Elemental analysis: found -C, 37.55 %; H, 3.06 %; N, 10.70 %. Calc. for C 12 H 12 AgN 3 O 5 -C, 37.33 %; H, 3.13 %; N, 10.88 %.
