1 Source of materials

The crystalline material was prepared by dissolving ((3a,7a-dihydro-1H-benzo [d][1,2,3]triazol-1-yl)methyl)triphenylphosphonium chloride (0.05 mmol) and manganese dichloride (0.05 mmol) in anhydrous ethanol (4.0 mL) within a 10 mL Schlenk tube. Concentrated hydrochloric acid (37 %, 0.50 mL) was added dropwise with stirring. The homogeneous solution was filtered through a 0.45 μm PTFE syringe filter into a clean 5 mL glass vial, which was subsequently placed inside a larger vessel containing 10 mL of diethyl ether as a reservoir for vapor diffusion. Crystallization occurred over 7 days at room temperature. Crystal dimensions were optimized by adjusting the evaporative flux through controlled needle aperture occlusion.

2 Experimental details

The structure was solved using intrinsic phasing methods within SHELXT. 2 Subsequent anisotropic full-matrix least-squares refinement on all non-hydrogen atoms was conducted using SHELXL 3 within the Olex2 platform. 4 Hydrogen atoms were incorporated at idealized positions employing riding models, with fixed isotropic displacement parameters.

3 Comment

Triphenylphosphonium (TPP) cations constitute a privileged class of supramolecular building blocks in crystal engineering, renowned for their capacity to direct hierarchical assembly through synergistic cation-π interactions, C–H⋯π contacts, and van der Waals forces. 5 , 6 , 7 , 8 The steric bulk and electronic anisotropy of TPP systems have been leveraged to construct functional materials with engineered void spaces, tunable luminescence, and proton-conducting behavior, as evidenced by structural studies of tetrafluoroborate and hexafluorophosphate analogues. Our elucidation of the single-crystal structure of ((3a,7a-dihydro-1H-benzo[d][1, 2,3]triazol-1-yl)methyl)triphenylphosphonium manganese tetrachloride represents the first systematic integration of benzotriazole-functionalized TPP cations with paramagnetic [MnCl4]2− moieties. The crystalline hybrid material exhibits prospects as a prototype for designing stimuli-responsive magnetic systems.

As illustrated in the Figure, the crystal structure of the title compound reveals a phosphorus atom bonded to four substituents: three phenyl groups and one 3a,7a-dihydro-1H-benzo[d][1,2,3]triazolyl group. The observed P–C bond lengths are approximately 1.80 Å, consistent with values reported in the literature for similar systems. 9 , 10 , 11 , 12 The interplanar angles between the three phenyl groups are 89.7°, 67.9°, and 87.9°, respectively. The dihedral angles formed between the 3a,7a-dihydro-1H-benzo[d][1,2,3] triazolyl group and each of the phenyl rings are 70.9°, 19.1°, and 83.6°.

Within the title compound, the [MnCl4]2− anion interacts with the triphenylphosphonium moiety, forming an organic-inorganic hybrid architecture (right side of the figure). The [MnCl4]2− anion exhibits a tetrahedral geometry, with Mn–Cl bond lengths averaging approximately 2.38 Å, in agreement with literature precedents. 13 , 14 , 15 , 16 The crystal structure features an alternating arrangement of these organic cations and inorganic anions.
