A lamella 2D silver(I) coordination polymer constructed from in situ generated 2-mercaptobenzoic acid

The reaction of Ag2O with 2,2′-dithiodibenzoic acid (dtba) under ultrasonic condition gave rise to a novel coordination polymer [Ag4(2-mba)2·(H2O)2]n (1) (2-H2mba = 2-mercaptobenzoic acid) involving in situ generated 2-mba. Complex 1 shows a lamella 2D structure with a 63-hcb net. Moreover, 1 exhibits photoluminescence and semiconductor properties.
