Syntheses and structural characterization of silver(I) complexes with pyridine and carboxylate derivatives

Self-assembly between silver carboxylates with 2-aminopyridine derivatives give two silver(I) complexes, [[Ag(5MP)(2)(CNB)] center dot NH3 (I) and [Ag(3MP)(2)(HMB)] (II), where 5MP, CNB, 3MP, and HMB represent 2-amin-5-methylpyridine, 5-chloro-2-nitrobenzoate, 2-amino-3-methylpyridine, and 2-hydroxy-3-methoxybenzoate, respectively. The crystal structures of the complexes were investigated. The Ag atom in each complex is coordinated by two pyridine N atoms and weakly coordinated by a carboxylic O atom. The crystal of I is triclinic: space group P (1) over bar a = 7.562(2), b = 11.708(3), c = 12.933(3) angstrom, alpha = 103.378(4)degrees, beta = 93.910(4)degrees, gamma = 99.001(4)degrees, V = 1093.7(5) angstrom(3), Z = 2. The crystal of II is monoclinic: space group C2/c, a = 25.727(5), b = 10.274(2), c = 19.872(4) angstrom, beta = 126.62(3)degrees, V = 4215.7(15) angstrom(3), Z = 4. DOI: 10.1134/ S107032841101009X
