| Abstract: | Solvothermal reactions of di-2-pyridyl ketone and cobalt carboxylates afford two novel tetra-and hexanuclear cobalt clusters,namely Co_4(OH){(py)_2CO(OH)}{(py)_2CO}(O_2CCMe_3)_6]·3H_2O 1 and Co_6{(py)_2CO(OH)}_2(O_2CMe)_8(DMF)(H_2O)_4]·DMF·H_2O 2.Crystal data for 1: monoclinic,P2(1)/n,a=1.57842(9),b=1.76781(9), c=2.26154(13) nm,V=6.2857(6) nm~3,F(000)=2712,final R_1=0.0651,wR_2=0.1764 I>2σ(I)].Crystal data for 2: monoclinic,P2(1),a=1.3721(4),b=1.4377(4),c=1.5541(5) nm,V=2.7813(14) nm~3,F(000)=2864,final R_1=0.0431,wR_2=0.1004I>2σ(I)].1 contains two edge-sharing Co_3O units with a butterfly structure,and 2 contains two fused linear arrays of three Co atoms with a "twin anchor" structure. |
