Representation of the X-ray structure of (tBu2Me2eda)Cu(nitro-BF) with nonhydrogen atoms shown as 50% thermal ellipsoids and tBu2Me2eda carbon atoms omitted for clarity. The monodentate (top) and bidentate (bottom) α-ketocarboxylate bound forms are shown. Selected interatomic distances (Å) and angles (deg): [Monodentate] Cu1-O1, 1.942(5); Cu1-O2, 2.981(6); Cu1-N1, 2.094(4); Cu1-N2, 2.087(4); O1-Cu-N1, 138.30(19)°; O1-Cu-N2, 119.1(5)°; N1-Cu-N2, 88.07(14)°; [Bidentate] Cu1-O1, 2.028(18); Cu1-O2, 2.344(16); Cu1-N1, 2.094(4); Cu1-N2, 2.087(4); N1-Cu-N2, 88.07(14); O1-Cu-N1, 139.1(5); O1-Cu-N2, 119.1(5); O2-Cu-N1, 124.9(5); O2-Cu-N2, 132.6(5).
