The hydrogen bonding between the 1-epialexine molecule and the water molecule of crystallization in (I), viewed down the unique axis, showing the C2 symmetry. The O14⋯N4 distance is 2.737 (2) Å and O14⋯O9 is 2.719 (2) Å for the Gemini–Cu data. [Symmetry codes: (ii) −x + , y − , −z + 1; (iii) x − , y − , z; (v) −x + 1, y, −z + 1.] |
