Crystal structures and photoluminescent properties of two d10 metal coordination polymers based on 5-aminodiacetic isophthalic acid

Based on the 5-aminodiacetic isophthalic acid (H4adip), two novel luminescent d10 metal coordination polymers have been successfully synthesized under hydrothermal conditions, namely, [Zn2.5(μ2-OH)(adip)(H2O)2]·3H2O (1), [Cd2(adip)(H2O)4]·2H2O (2). Compound 1 is a two-dimensional network structure based on the metal five-nuclear subunits. It is extraordinary that 2 is a three-dimensional structure containing two different kinds of pores, the dimensions of the pores are 11.46 × 11.13 Ǻ and 11.43 × 7.49 Ǻ, respectively. The photoluminescent properties of 1–2 were further investigated.
