Fig. 3. ORTEP style representation of 2 (hydrogen atoms omitted for clarity) with ellipsoids drawn at the 50% probability level. The complex features an intramolecular centre of inversion. Disordered groups are indicated by thin bonds. Selected bond lengths (Å) and bond angles (deg): Zn1–Zn2 2.9486(4), Zn1–N1 2.035(1), Zn1–N2 2.029(1), Zn1–O1 1.966(1), Zn1–O1A 2.019(1), N1–Zn1–N2 94.36(5), O1–Zn1–N2 120.97(5), O1–Zn1–N1 126.35(5), O1–Zn1–O1A 84.55(4).
