Synthesis and Crystal Structure of (PzCH₂CHOHCH₂PzH)·(Ph₂SnCl₃) (Pz = 3,5-dimethylpyrazol-1-yl)

Abstract

Reaction of Ph₂SnCl₂ with 1,3-bis(3,5-dimethylpyrazol-1-yl)-2-propanol (L) in a 1:1 ratio yields L(SnPh₂Cl₂)₂ adduct, which partly hydrolyzes to the title complex (C₂₅H₃₁Cl₃N₄OSn, Mr = 628.58) during crystal growing in the air. The title complex is of monoclinic, space group P2₁/n with a = 9.0338(9), b = 17.890(1), c = 17.340(1) Å, β = 95.533(1)^o, V = 2798.9(5) Å³, Z = 4, Dc = 1.492 Mg/m³, λ(MoKα) = 0.71073 Å, μ = 1.224 mm⁻¹, F(000) = 1272, R = 0.023, wR = 0.054 for 4212 observed reflections with I ≥ 2σ(I). The crystal structure indicates that there is no direct interaction between the pyrazolyl ligand and the tin atom, but this complex forms a supramolecular structure through weak intermolecular C–H⋯Cl and O–H⋯Cl hydrogen bonds.
