Overview

The reaction between two equivalents of dimethyl N -cyanodithioiminocarbonate, [(MeS) 2 C=N–C≡N] ( 1 ), one equivalent of n -butyltin trichloride, Sn( n -Bu)Cl 3 and one equivalent of sodium hydroxide, NaOH led to isolation of a dinuclear complex {[Sn( n -Bu)Cl 2 (OH)(H 2 O)] 2 } ( 2 ) which co-crystallized with four [(MeS) 2 C=N–C≡N] molecules, {[Sn( n -Bu)Cl 2 (OH)(H 2 O)] 2 [(CH 3 S) 2 C=N–C≡N] 4 } ( 3 ). The compound was investigated by single-crystal X-ray diffraction analysis and infrared spectroscopy. Compound 3 crystallizes in the triclinic space group P 1 ¯ with a  = 9.8208(15), b  = 11.2664(17), c  = 12.0446(18) Å, α  = 106.236(5), β  = 111.510(5), γ  = 97.710(6)°, V  = 1147.9(3) Å 3 , Z  = 1 and Z′ = 0.5. In the complex, two aqua- n -butyltinhydroxide dichloride moieties, [Sn( n -Bu)Cl 2 (OH)(H 2 O)], are bridged by the hydroxides. The hydroxide bridges bond lengths describe a static trans effect yielding a dissymmetry in Sn–O bonding. Two inner O2–H2D⋯Cl1 hydrogen bonds strengthen the dinuclear component. The dimethyl N -cyanodithioiminocarbonate molecules are linked to the dinuclear component through the hydroxide bridges and the water molecules by O1–H1⋯N2A and O2–H2C⋯N2B hydrogen bonding patterns of D type, respectively. The [(MeS) 2 C=N–C≡N] molecules exhibit a positional disorder. These hydrogen bonding interactions lead to cyclic patterns generating R 1 1 (6) and R 2 2 (8) rings. Additional C–H⋯Cl and C–H⋯N hydrogen bond patterns also contribute to the crystal structure framework: they give rise to a 3D structure. Graphical Abstract Reacting with n -BuSnCl 3 and NaOH in an aqueous mixed solvent, dimethyl N -cyanodithioiminocarbonate, (MeS) 2 C=N–C≡N forms a co-crystalline 4:1 assembly with the bimetallic organotin(IV) complex, [Sn( n -Bu)Cl 2 (OH)(H 2 O)] 2 , whose single crystal XRD analysis exhibits a 3D hydrogen bonded structure.
