Figure 1
The coordination environment of the linear pentanuclear unit of (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 50% probability level. Both positions of disordered atoms O1 and N6 are shown. [Symmetry codes: (i) −x, −y + 2, −z + 1; (ii) x, y + 1, z; (iii) −x + , y − , −z + ; (iv) −x, −y + 1, −z + 1; (v) x, y − 1, z.] |
