title: First 3D Pr(III)-Ni(II)-Na(I) polymer and a 3D Pr(III) open network based on pyridine-2,4,6-tricarboxylic acid.
abstract: The self-assembly of pyridine-2,4,6-tricarboxylic acid (H(3)ptc) with metal salts under hydrothermal conditions gave two novel coordination polymers, {[Pr(mu(5)-ptc)(H(2)O)(2)].1.5H(2)O}(n)() (1) and {Na(2)NiPr(mu(4)-ClO(4))(mu(2)-HOCH(2)CH(2)OH)(mu(4)-ptc)(2)(H(2)O)(8)}.4.5H(2)O}(n)() (2). 1 is a 3D open network with five ptc ligands coordinating with one metal center and carboxylate groups linking metal centers to form a (4,6) net. 2 is the first Pr/Ni/Na heterotrimetallic complex, a unique 3D framework containing four different bridged ligands in the system.
