Abstract:
In the asymmetric unit of title coordination polymer, {(C(16)H(36)N)[Zn(3)(C(9)H(3)O(6))(2)(OH)]·0.25H(2)O}(n), there are three independent Zn(2+) cations, two benzene-1,3,5-tricarboxyl-ate ligands and a μ(3)-bridging hydroxide group, together with a tetra-n-butyl-ammonium counter-cation and a partially occupied water molecule of solvation (occupancy 0.25). Each Zn ion is coordinated by three carboxyl-ate O atoms and one O atom from the bridging hydroxide ion, displaying a slightly distorted tetra-hedral stereochemistry [overall Zn-O range = 1.875 (3)-1.987 (2) Å]. An intra-molecular hydrogen bond involving the hydroxide H atom and a carboxyl-ate O-atom acceptor is also present in the complex unit. The bridging benzene-1,3,5-tricarboxyl-ate anions generate a three-dimensional framework structure.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
