“…Thus, Λ-stacking occurs between the 2,2'-bipyridyne ligands of the helicates. Such interactions are common in organometallic or DNA helices [23][24][25]. The handedness of the helices is induced by the intrinsic character of helicates: the enantiomer leads to the 31 helices while the Δ enantiomer leads to the 32 helices.…”

Chiral structures resulting from the packing of helices are common in biological and synthetic materials. Herein, we analyze the noncentrosymmetry (NCS) in such systems using crystallographic considerations. A comparison of the chiral structures built from helices shows that the chirality can be expected for specific building units such as 3 1 /3 2 or 6 1 /6 5 helices which, in hexagonal arrangement, will more likely lead to a chiral resolution. In these two systems, we show that the highest crystallographic symmetry (i.e., the symmetry which can describe the crystal structure from the smallest assymetric unit) is chiral. As an illustration, we present the synthesis of two materials ([Zn(2,2'-bpy) 3 ](NbF 6 ) 2 and [Zn(2,2'-bpy) 3 ](TaF 6 ) 2 ) in which the 3 n helices pack into a chiral structure.

“…Inorganic complex anions with NCS À , CN À and SCN À are proved to be very useful and potential building block for organic-organic hybrid materials [7]. Particular attention has been focused on [M(CN) 6 ] nÀ (M = Co 3+ , Cr 3+ , Fe 2+ , Fe 3+ , Mn 3+ , n = 3 or 4) [8], while the literature covering the organic-organic hybrid materials containing tetra(isothiocyanate)cobalt(II) anion and organic cation is scarcer [9][10][11][12]. Recently, we have employed substituted benzyl triphenylphosphinium derivatives abbreviated as ([RBzTPP](R = H, Cl, CN, TPP = triphenylphosphine) as multifunctional cation and the [Ni(mnt) 2 (2), and their crystal structures and magnetic properties have been investigated.…”

“…In particular, the inherent coordination angle of the isothiocyanate species leads to a wide range of various molecular solids containing [M(NCS) 4 ] 2− (M = Mn 2+ , Co 2+ , Zn 2+ ), which may exhibit interesting magnetic behaviors, electronic, and optical properties [11][12][13][14][15]. The selection of the counter organic cation is of key importance as it controls the stacking of the whole molecule, and the non-covalent interactions (such as weak p···π/π···π stacking interactions and hydrogen bonds) also play an important role in the arrangement of the structural units of molecular solids [16][17][18]. Our previously published studies have been devoted to the syntheses, X-ray single crystal structures, spectroscopic studies, magnetic or fluorescent properties of hybrid materials based on the tetra(isothiocyanate)cobalt/zinc anion and substituted benzyl triphenylphosphonium cations.…”

Abstract:Single crystals of two hybrid organic-inorganic molecular solids, benzyl pyridinium tetra(isothiocyanate)cobalt ([BzPy] 2 [Co(NCS) 4 ]) (1) and benzyl quinolinium tetra(isothiocyanate)cobalt ([BzQl] 2 [Co(NCS) 4 ]) (2), were grown using a slow evaporation growth technique at room temperature and their IR, UV-Vis, X-ray crystal structures, luminescence, and magnetism were reported. The crystal structural analysis revealed that two molecular solids crystallize in the monoclinic space group P2 1 /c of 1 and P2 1 /n of 2. The cations form a dimer through weak C-H···π/π···π interactions in 1 and 2, and the adjacent cation (containing N(6) atom) in 2 forms a columnar structure through π···π weak interactions between the quinoline and benzene rings, while the anions in 1 form a layer structure via short S···Co interactions. The anions (A) and cations (C) are arranged alternatively into a column in the sequence of ···A-CC-A-CC-A··· for 1, while the two anions and cationic dimer in 2 form an alliance by the C-H···π, C-H···S and C-H···N hydrogen bonds. A weak S···π interaction was found in 1 and 2. The two molecular solids show a broad fluorescence emission around 400 nm in the solid state at room temperature, and weak antiferromagnetic coupling behavior when the temperature is lowered.
