It aims to construct highly complex, functional chemical systems from components held together by intermolecular interactions. Various supramolecular interactions are used as tools in crystal engineering in order to develop novel functional materials.1 Recently, in addition to the well developed molecular interactions and conformational studies on N-alkylammonium halides (mono, di, tri-alkylammonium halides) complexes with nonplanar aromatic molecules in respect to knowing the inter, and intra-molecular interactions and preferred conformation exhibited by both the non-planar aromatic molecule and the alkyl chain, much interest has been shown by various researchers due to its useful applications in separation science and crystal engineering.2,3 Our group of researchers have been recently involved in examining the preferential conformation of non-planar aromatic molecules and the alkyl chain in crystal complexes involving tetra-n-alkylammonium halides (n = 4, 5,···) with non-planar aromatic molecules in order to exploit probable conformational adjustments that could occur due to effect of increases in chain length and changes of the counter anion in the hydrogen-bonded binaphthol cavity environ. It has been shown by our group that crystal complexes of tetrabutylammonium halides (R4N·X, where R = butyl, and X = Br or Cl, hereafter TBAB, or TBAC, respectively) with rac-1,1′-bi-2-naphthol (hereafter, BNP) are isomorphous.4 In both crystal structures (TBAB/BNP and TBAC/BNP) the alkyl chains exhibit conformational and orientational disordered structures, while in a tetrapentylammonium bromide (R = pentyl, hereafter, TPAB) complex with BNP (hereafter, TPAB/BNP), the biradial conformation is exhibited by the alkyl chains.5 Per this knowledge we were challenged to investigate how changes of the counter anion from Br– to Cl– as well as an increase in the alkyl chain from n = 4 to 5 can also generate any conformational adjustments in both the binaphthol molecules or the alkyl chains. Interestingly, in an attempt to obtain a TPAC/BNP crystal complex, the crystal complex entrapped solvent (acetonitrile) molecules, as per revealed by X-ray crystallography studies.

To prepare a zero-field SIM, not only a strong magnetic anisotropy, but also the molecular alignment of SIMs in the crystal, is important. Recently, zero-field SIM behavior in pseudo-tetrahedral cobalt(II) complexes with 2-(2-imidazolinyl)-6-methoxyphenolate (Hmimn–) was reported.4 It was suggested that hydrogen-bonded chain networks of [Co(Hmimn)2] play a crucial role for slow magnetic relaxation in the absence of an external field. To elucidate the correlation between intermolecular magnetic coupling and quantum tunneling of magnetization, partial substitution of a paramagnetic ion by a diamagnetic ion in the crystal is an effective method.

Recently, we have reported the formation of crystal complex involving rac-1,1′-binaphthalene-2,2′-diol (hereafter, BNP) with benzyltrimethylammonium chloride (hereafter, BTMAC) in which the phenyl group in the arylammonium salt controlled the directionality of the methyl groups to generating weak H-bonds that played relevant roles in crystal complexation, stabilizing the crystal structure, as well as enhancing the molecular recognition phenomenon in the supramolecular structure. Thus, we found it prudent to investigate the structure of the benzyltrimethylammonium bromide (hereafter, BTMAB) complex with (R)-(+)-1,1′binaphthalene-2,2′-diol (hereafter, RBNP) in order to know the effect of changing from the chloride (Cl–) to bromide (Br–) in the arylammonium salt, as well as altering from racemic to (R) form of (+)-1,1′-binaphthalene-2,2′-diol on such a supramolecular system with respect to knowing the packing structure, and interactions in the molecular recognition phenomenon that may exist in the BTMAB/RBNP complex. Gratifyingly, we have solved the crystal structure, analyzed and discussed herein.
