Every sodium ion coordinates in trigonal prismatic fashion with two O atoms from a terminal chelating catecholato ligand and four O atoms from bridging P2 catecholato ligands, Two neighboring NaO6 trigonal prisms are face-shared and centrosymmetric with regard to the inversion center consisting of four tri-bridging O atoms to form a binuclear cluster {Na2μ2-（C6H4O2）2]}^2- anion. The comparison of ^13C NMR spectrum of tlie complex in solid state with that in solution indicated that the rapid exchange between the bridging μ2-（C6H4O2]^2- and terminal C6H4OOH]^- ligands was present in solution.

| Abstract: | The new compound (NH3CH2CH2NH3)2{Na2μ2‐(C6H4O2)2](C6H4OOH)2} has been synthesized and characterized by elemental analysis, IR, UV, NMR and single crystal X‐ray diffraction. The yellow crystals crystallized in the triclinic system with space group P‐1 and a=0.6091(2) nm, b=1.0274(3) nm, c=1.2466(4) nm, α=89.073(6)°, β=89.376(6)°, γ=78.873(5)°, V=0.7653(4) nm3, Z=1, R1=0.0568, wR2=0.1198. Every sodium ion coordinates in trigonal prismatic fashion with two O atoms from a terminal chelating catecholato ligand and four O atoms from bridging µ2 catecholato ligands. Two neighboring NaO6 trigonal prisms are face‐shared and centrosymmetric with regard to the inversion center consisting of four tri‐bridging O atoms to form a binuclear cluster {Na2μ2‐(C6H4O2)2]}2? anion. The comparison of 13C NMR spectrum of the complex in solid state with that in solution indicated that the rapid exchange between the bridging μ2‐(C6H4O2)]2? and terminal C6H4OOH]? ligands was present in solution. |
