Two new hybrid organic-inorganic salts, [BzDMAP] 2 [Cu(mnt) 2 ](1) and [NO 2 BzDMAP] 2 [Cu(mnt) 2 ](2) ([BzDMAP] ? = 1-benzyl-4 0 -dimethylaminopyridinium, [NO 2 BzDMAP] ? = 1-(4 0 -nitrobenzyl)-4 0 -dimethylaminopyridinium, and mnt 2-= maleonitriledithiolate) have been characterized structurally and magnetically. The [BzDMAP] ? or [NO 2 BzDMAP] ? cations (C) and the [Cu(mnt) 2 ] 2-anions (A) in 1 and 2 stack into a 1D alternating CC-A-CC-A-CC column. The CuÁÁÁN, pÁÁÁp, C-HÁÁÁN, C-HÁÁÁO, and C-HÁÁÁS weak interactions play important roles in the molecular stacking and generate a 2D or 3D structure of 1 and 2. The magnetic susceptibilities of these salts measured in the temperature range 2.0-300 K show weak antiferromagnetic coupling features with h = -2.370 K for 1 and -0.222 K for 2.

Two new salts, [oClBzTPP] 2 + [Ni(mnt) 2 ] 2-(1) and [oClBzTPP] + [Ni(mnt) 2 ] - (2) ([oClBzTPP] + = 1-(2 0 -chlorobenzyl)triphenylphosphonium and mnt 2-= maleonitriledithiolate) have been prepared and characterized by elemental analyses, UV, IR, MS spectra, single crystal X-ray diffraction, and magnetic susceptibility. The Ni ions of the Ni(mnt) 2 anions for 1 and 2 exhibit the square-planar coordination geometry. The Ni(III) ions of 2 form a 1D zigzag alternating magnetic chain within a Ni(mnt) 2 -column through NiÁÁÁS, SÁÁÁS, or NiÁÁÁNi interactions. The C-HÁÁÁN, C-HÁÁÁS, C-HÁÁÁp hydrogen bonds or pÁÁÁp stacking interactions play important roles in the molecular stabilizing and stacking of 1 and 2. Magnetic susceptibility measurements in the temperature range 1.8-300 K show that 2 exhibits diamagnetic behavior.

“…Benzyl pyridinium bromide ([BzPy]Br) and benzyl quinolinium bromide (BzQl)Br) were prepared using the published methods in Reference [33]. The blue crystals suitable for X-ray structural analysis were obtained by evaporating the MeOH solution of 1 and 2 for around two weeks at room temperature.…”

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.
