Source of material

The title compound has been synthesized according to the following method: 0.2003 g (1.0 mmol) 4,4-dihydroxydiphenylmethane and 0.1842 g (1.0 mmol) 1,2-bis(4-pyridyl)ethane were successively added to 20 mL methanol-water (v:v = 1:1). The solution was allowed to stand at room temperature for three days, colorless block crystals were obtained.

Experimental details

The structure was solved by direct methods with the SHELXS program. All H-atoms at C atoms were positioned with idealized geometry and refined isotropically (U iso (H) = 1.2U eq (C), using a riding model with C–H = 0.93Å or 0.96 Å. H atoms attached to O atoms were found in a difference Fourier synthesis and were refined using a riding model, with the O–H distances fixed as initially found and with U iso (H) values set at 1.5U eq (O).

Comment

Organic cocrystals, composed of two or more molecular and/or ionic compounds in a stoichiometric ratio, are crystalline or single-phase materials [4], [5]. Over the past decades, they have attracted wide attention and emerged as a promising research interest to construct functional materials due to their unique electrical, magnetic, and optical properties [6], [7], [8]. Crystallization is a typical self-assembly phenomenon [9]. The synergistic effect of those non-covalent bonding interactions between homomeric and heteromeric molecules governs recognition and assembly process [10], [11], [12], [13], [14]. The synthon that is formed between bisphenol and other moieties is one of the most exploted synthon for designing cocrystal [15], [16], [17], [18], [19].

The asymmetric unit of the title structure contains one half of a 4,4′-dihydroxydiphenylmethane molecule and one half of a 1,2-bis(4-pyridyl)ethane molecule (see the figure). Bond lengths and angles are within normal ranges. In the crystal structure of the title complex, O–H⃛N hydrogen interactions (O1⃛N1 = 2.759(6) Å; O1–H1B⃛N1 = 177.1°) between the 4,4′-dihydroxydiphenylmethane and 1,2-bis(4-pyridyl)ethane molecules lead to the formation of a chain along the c axis. Two pyridine groups of neighboring molecules, related by inversion symmetry are involved in a π-π interaction with a centroid-centroid distance of 3.78 Å forming a two-dimensional layer structure parallel to (100).
