Abstract
The synthesis and X-raystructural characterization of two novel silver(I) coordination polymers, [Ag (NO3)(quin)]n (1) and[Ag8(HL)2(H2O)4(mpyz)] . 3H2O (2) arereported, wherequin= 5,6,7,8-tetrahydro- quinoxaline, H6L = cyclohexane-1,2,3,4,5,6-hexacarboxylic acid andmpyz = 2-methylpyrazine.The single crystal diffractionan alyses showed that complex 1 is a 2D layered structure, while 2 presents a 3D polymeric architecture .In complex 2 the network is stabilized by argentophilic interactions and hydrogen bonding. Electrical conductivity of order 3x10-4 S cm-1 (1) and1.6x10-4 S cm-1 (2) is measured on thin film specimen at room temperature.The photoluminescence and thermal properties of the complexes have also been studied.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
