Figure 2
(a) The asymmetric unit of complex (II)[link] represented with displacement ellipsoids at the 50% probability level. H atoms not involved in hydrogen bonding are omitted for clarity. The donor–acceptor distances are shown as green for intra­molecular hydrogen bonds and shown as blue for inter­molecular hydrogen bonds (O10–O15) and inter-asymmetric unit hydrogen bonds (O9 –O13). Additional symmetry-related atoms O10 and O15 were generated by the symmetry operator 1 − x, −y, 1 − z, and O9 and O13 were generated via the inversion center 1 − x, 1 − y, 1 − z at the center of the hexa­nuclear complex. (b) The asymmetric unit of complex (II)[link] oriented to show donor–acceptor distances of intra­molecular hydrogen bonds, in green, of the protonated dhbp ligands.
