Abstract The manganese complex, [Mn(III)(Hvanpa)2]N3 has been prepared and the crystal structure determined using x-ray crystallography. The mononuclear complex has a six-coordinate octahedral geometry. The complex crystallizes in the monoclinic space group P21/c with a = 9.867(1), b = 13.316(2), c = 9.0110(1) Å, β = 107.870(1)°, V = 1126.8(2) Å3, and Z = 2. The Mn-O and Mn-N distances in the equatorial plane are in good agreement with those found for other manganese(III) Schiff base complexes. In the axial direction, the Mn-O distances of 2.274(2) Å is about 0.3 Å longer than those in the equatorial plane due to a Jahn-Teller distortion at the d4 manganese(III) center. In the crystal, each azido ion is linked through hydrogen bonding with two hydrogen atoms from the coordinate hydroxyl groups at the apical site.
