Key indicators: single-crystal X-ray study; T = 293 K; mean (C-C) = 0.005 Å; R factor = 0.041; wR factor = 0.083; data-to-parameter ratio = 12.5. The title compound, [Co 3 (C 25 H 20 N 2 O 2 ) 2 (C 2 H 3 O 2 ) 2 ], is an acetate-and phenolate-bridged trinuclear cobalt(II) complex. The central Co atom, lying on an inversion centre, is in an octahedral geometry. Each terminal Co atom is in a squarepyramidal geometry. 2 ] M r = 1055.74 Monoclinic, P2 1 =n a = 11.770 (3) Å b = 11.765 (4) Å c =
