Fig. 1. Crystal structures of complex 1 (a) coordination mode (symmetry code: (i) −x + 2, −y + 1, −z), hydrogen atoms are omitted for clarity. (b) 1D chain formed via hydrogen bonds. Terminal butyl groups of the ligands are omitted for clarity (symmetry code: (ii) −x + 1, −y + 1, −z; (iii) x + 1, y, z; (iv) x − 1, y, z). (c) Crystal packing along the a-axis.
