✦ Synopsis

In the title mononuclear complex, [Cu(ClO 4 ) 2 (C 5 H 4 N 2 O 3 ) 4 ], the six-coordinated Cu II ion lies on an inversion centre and presents a slightly distorted octahedral geometry. Astacking interaction is observed between symmetry-related pyridine rings.

The bis(4-ethylpyridine) adduct of dicopper(II) tetrabenzoate, [ Cu 2 (C 7 H 5 O 2 ) 4 (C 7 H 9 N) 2 ], has centrosymmetrically related square-pyramidal Cu atoms bridged by four benzoate ions; the heterocyclic ligands that occupy the apical sites are disordered.

The title compound, [Cu 2 (C 5 H 9 O 2 ) 4 (C 5 H 5 N) 2 ], consists of centrosymmetric binuclear cage units with four dimethylpropanoate bridges linking the two Cu centres [CuÁ Á ÁCu = 2.6229 (9) A ˚]. The square-pyramidal Cu coordination is completed by a pyridine N atom at the apical site. Astack
