Two novel L-amino alcohol coordination cobalt and copper complexes Ⅰ and Ⅱ were obtained separately from the direct reaction of L-plenylglycinol with Co(Ⅱ) acetate tetrahydrate in anhydrous ethanol and L-leucinol with Cu(Ⅱ) chloride dihydrate in anhydrous methanol. The structures of Ⅰ and Ⅱ were determined by single-crystal X-ray diffraction and further characterized by elemental analysis and IR. For Ⅰ: [Co₃(C₅₁H₆₆N₃O₁₆)]₂(OAc), monoclinic, space group P2₁, a=15.022(3), b=14.242(3), c=28.922(6)Å, β=98.944(4)°, V=6112(2)Å³, Z=4, D_c=1.339 g/cm³, the final R=0.0860 for 21906 observed reflections with I>2σ(I). For Ⅱ: Cu₂[C₂₄H₅₈N₄O₇Cl]Cl, orthorhombic, space group P2₁2₁2₁, a=6.1861(13), b=20.838(4), c=28.274(6)Å, V=3644.6(13)Å³, Z=4, D_c=1.310 g/cm³, the final R=0.0642 for 11106 observed reflections with I>2σ(I). The complexes were then used to catalyze the Henry reaction and catalytic activity determined by ¹H NMR.
