Two Novel Metal−Organic Frameworks (MOFs) with (3,6)-Connected Net Topologies: Syntheses, Crystal Structures, Third-Order Nonlinear Optical and Luminescent Properties

Abstract

Two novel metal−organic frameworks (MOFs) [Cu3(C7H2NO5)2]n·3nH2O (1) and [CuAg2(C7H3NO5)2]n (2) were obtained by the hydrothermal reaction. Complex 1 exhibits a three-dimensional (3,6)-connected anatase topology with the Schläfli symbol (42.6)2(44.62.88.10), while complex 2 displays a two-dimensional (3,6)-connected TiS2 related net topology with the Schläfli symbol (43)2(46.66.83). The optical studies show that 1 and 2 both have good third-order nonlinear optical and luminescent properties.
