Figure 1
The mol­ecular structure of (I)[link]. Displacement ellipsoids are drawn at the 40% probability level. Independent atoms are shown with solid bonds and shaded ellipsoids, while symmetry-related atoms have hollow bonds and boundary ellipsoids. Hydrogen bonds are shown as dashed lines. For clarity, only those H atoms involved in hydrogen bonding are shown. Cg1, Cg2 and Cg3 are the centroids of the N11/C21/N31/C41/C51, N12/C22/N32/C42/C52 and N13/C23/N33/C43/C53, rings, respectively. Label `A' denotes the centrosymmetric Cu2O2 diamond-like motif. [Symmetry codes: (i) −x + 2, y + [{1\over 2}], −z + [{1\over 2}]; (ii) −x + 2, −y + 1, −z + 1; (iii) x, y + 1, z; (iv) −x + 2, y − [{1\over 2}], −z + [{1\over 2}].]
