Abstract

Porous Cu-Cd mixed-metal-organic frameworks [[Cd(NO(3))(2)](2)[(Cu(Pyac)(2)](3)] (M'MOF 1) and [[CdCl(2)][Cu(Pyac)(2)](2)] (M'MOF2) [Cu(Pyac)(2) = bis[3-(4-pyridyl)pentane-2,4-dionato]copper(II)] have been synthesized by the reaction of Cu(Pyac)(2) with Cd(NO(3))(2) and CdCl(2). They are noninterpenetrating 1D ladder and 2D square-grid frameworks, constructed from Cu(Pyac)(2) building blocks with T-shaped Cd(NO(3))(2) nodes and square-planar CdCl(2) nodes, respectively. The 1D ladders and 2D square grids are stacked in ABCABC... and ABCDEF... packings, leading to 2D interconnected channels of ca. 5.7 x 10.2 and 4.1 x 9.8 A in 1 and 1D channels of ca. 8.0 x 8.2 A in 2, respectively. The copper sites in these two M'MOFs are coordinated by solvent molecules and exposed to the pores.
