Di-μ-aqua-bis-[aqua-(2,2′-bi-pyridine)(4-nitro-benzoato)cobalt(II)] bis-(4-nitro-benzoate)

摘要

The title compound, [Co 2 (C 7 H 4 NO 4 ) 2 (C 10 H 8 N 2 ) 2 (H 2 O) 4 ](C 7 H 4 NO 4 ) 2 , consists of a centrosymmetric bimetallic complex charge-balanced by free 4-nitro-benzoate anions. The Co II ion exhibits a distorted cis -CoN 2 O 4 octa-hedral coordination environment and the Co?Co separation is 3.326?(2)??. In the crystal, the dications and anions are linked by O—H?O and C—H?O hydrogen bonds.
