“…Within each pair, the complexes interact via a combination of OFF and edge-to-face (EF) interactions known as a parallel 4-fold aryl embrace (P4AE). 25 The halogen-bonded ribbons of DITFB (2). In the crystal structure, discrete 4-component supramolecular complexes are formed, each consisting of a linear halogen-bonded sequence of monotopic 1,2-DITFB, ditopic iodide (I2), ditopic 1,2-DITFB and monotopic iodide (I1) (Figure 2(a)).…”

“…The exceptions have primarily involved halogen bond interactions between sites on two ligands (M–L···L–M), or between a ligand and a discrete organic molecule (M–L···X–Org), with the focus mainly on halide, cyano, and cyano-functionalized ligands. Many of the known examples of metal complexes participating in halogen bonding are serendipitous, rather than designed, and the earliest report of such a system, to our knowledge, refers to the unexpected formation of an iodoperfluorobenzene adduct with trans -diiodobis(1,2-dimethoxyethane)nickel(II). , …”

The complex must contain at least one accessible halogen bond donor or acceptor site, restricting structural variability in the toolbox of viable building blocks.…”

Combining [Ni(phen)3]I2 or [Ni(phen)3]Cl2 (phen = 1,10-phenanthroline) with the iodoperfluorobenzenes (IPFBs), 1,2-, 1,3-, 1,4-diiodotetrafluorobenzene (1,2-, 1,3-, and 1,4-DITFB, respectively), or 1,3,5-triiodotrifluorobenzene (1,3,5-TITFB) resulted in the formation of six different cocrystalline materials featuring halogen-bonded networks encapsulating [Ni(phen)3]2+ ions. The cocrystals have the general formula [Ni(phen)3][(IPFB) n (X2)(L) m ]·solvate (n = 2 or 3; X = Cl– or I–; L = halogen-bonded H2O and/or MeOH; solvate = isolated H2O and/or MeOH). The halide ions balance the charge of the metal complexes and simultaneously act as halogen bond acceptors for the electronically polarized iodine atoms of the IPFB donors. The structures display a wide variety of supramolecular motifs in the context of both the aggregation of the metal complexes and the topology and connectivity of the halogen bond networks. The well-known supramolecular “aryl embrace” motifs of [Ni(phen)3] complexes are present but are structurally compromised to varying degrees in the crystals of [Ni(phen)3][(1,2-DITFB)2I2]·MeOH, [Ni(phen)3][(1,3-DITFB)2I2]·2MeOH, and [Ni(phen)3][(1,3-DITFB)2(H2O)2Cl2]·1.5MeOH. In [Ni(phen)3][(1,3-DITFB)3I2], the [Ni(phen3]2+ complexes are so thoroughly enclosed in halogen-bonded networks that the metal complexes have no significant supramolecular contact. In contrast, in [Ni(phen)3][(1,4-DITFB)3I2(MeOH)0.5] and [Ni(phen)3][(1,3,5-TITFB)2Cl2] the complexes are arranged in typical aryl embrace motifs (pairwise and 1D chains, respectively), but with adjacent complexes held in closer proximity to each other than they reside in crystals of the pure metal complex. The interplay between the supramolecular chemistry of the halogen-bonded networks and the metal complexes was examined in detail, and the results demonstrate that it is possible to significantly influence the aggregation of metal complexes by encapsulation in different halogen bond networks.

Eine systematische Untersuchung der elementaren Zusammensetzung des Reaktionsgemisches, das sich aus Ni(CO)4, 1,2‐Diiodtetrafluorbenzol und 1,2‐Dimethoxyethan als Lösungsmittel bei 120°C bei Verwendung verschiedener molarer Verhältnisse ergibt, zeigt, daß bei niedriger Konzentration, wenn das Verhältnis von Halogenbenzol zu der Ni‐Verbindung mehr als drei beträgt, die kristalline Titelverbindung entsteht.
