The title complex is orthorhombic, space group P212121, with a 0.8844(2), b 1.6286(4), and c 1.7751(5) nm; dc = 1.33 for Z = 4. Final R = 5.8% (Rw = 4.7%) for 2604 reflections. Atomic coordinates are given. The Cu environment of the complex is a distorted tetrahedral conformation. The angle between the plane defined by the N(1)-Cu-O(1) and N(2)-Cu-O(2) groups is ~39.3? The a-methylbenzyl groups point to the same side of the approx. Cu,N(1),O(1),N(2),O(2) ligand plane (cis), and they are roughly perpendicular to the remainder of the mol. and roughly perpendicular to each other.
