Figure 2 A zigzag hydrogen bonding chain along the b axis is shown in the crystal packing of the title compound. Dashed lines indicate hydrogen bonds. Symmetry operations: A = −x − $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; B = −x − $[{1\over 2}]$ , y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ .
