Topological studies of three related metal-organic frameworks of GdIII and 5-nitroisophthalate
Journal article, 2012

The reaction of 5-nitroisophthalic acid (H(2)NIA) with Gd(NO3)(3)center dot 6H(2)O in DMF afforded three new metal-organic frameworks: [Gd(NIA)(1.5)(DMF)(2)]center dot DMF (I), [Gd-2(NIA)(3)(DMF)(4)]center dot xH(2)O (II) and [Gd-4(NIA)(6)(DMF)(5.5)(H2O)(3)]center dot 4DMF center dot H2O (III). These compounds can be prepared through a variety of methods. Compounds (I) and (II) are more reproducibly formed than compound (III). Network analysis revealed (I) to have a (4(12).6(3))-pcu topology, while (II) displays a (4(2).8(4))(4(2).8(4))-pts topology. Compound (III) was found to present the uncommon 4,5,6T11 topological net, which combines aspects of both the pcu and pts topologies. The short symbol of this net is (4(4).6(2))(4(6).6(4))(2)(4(8).6(6).8).
