Figure 1
The structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 30% probability level. Only one position of disordered atom Cu1 is shown. The single dashed line indicates a hydrogen bond and the double dashed line indicates an intermetallic contact. [Symmetry codes: (A) −x + , −y + , −z + 1; (B) −x + 1, y, −z + .] |
