Abstract

A six connected 3D porous coordination polymer {[Cd(HBTC)(BPz)]·3EtOH}n (1) (H3BTC = benzene-1,3,5-tricarboxylic acid, BPz = 3,3′,5,5′-tetramethyl-4,4′-bipyrazole) has been synthesized from mild solvothermal reaction of Cd(NO3)2·4H2O with BPz and H3BTC in ethanol. Complex 1 is a thermally stable microporous MOF having (Cd2(COO)2) as the secondary building unit (SBU) with a six connected pcu topology. The pores of the polymer are decorated with free COOH groups which show moderate N2 sorption (38 cc g− 1) at 77 K with a BET surface area of 129 m2 g− 1. Complex 1 also exhibited photoluminescent property in solid state with λmax at 396 nm.
