Summary
This study confirms previous findings on the tin complex [Sn(C(6)H(5))(3)(C(7)H(4)NO(4))] at room temperature. A weak tin-oxygen interaction creates a distorted trigonal-pyramidal geometry around the tin atom.
Area of Science:
- Organometallic Chemistry
- Crystallography
- Coordination Chemistry
Background:
- Previous structural analysis of [Sn(C(6)H(5))(3)(C(7)H(4)NO(4))] was conducted at 173 K.
- Understanding the structural behavior of organotin compounds is crucial for various applications.
Purpose of the Study:
- To confirm the previously determined crystal structure of [Sn(C(6)H(5))(3)(C(7)H(4)NO(4))] at 298 K.
- To elucidate the coordination environment of the tin atom in the solid state.
Main Methods:
- Single-crystal X-ray diffraction at 298 K.
- Comparison with existing crystallographic data at 173 K.
Main Results:
- The crystal structure of [Sn(C(6)H(5))(3)(C(7)H(4)NO(4))] at 298 K was fully determined.
- The structure confirms the findings from the 173 K analysis.
- A weak interaction between the tin (Sn) atom and a carbonyl oxygen atom of the benzoate ligand was observed.
- This interaction results in a distorted trigonal-pyramidal geometry around the Sn atom, deviating from its pseudo-tetrahedral primary coordination.
Conclusions:
- The structural integrity of [Sn(C(6)H(5))(3)(C(7)H(4)NO(4))] is maintained at both low and ambient temperatures.
- The observed weak Sn-O interaction plays a significant role in defining the tin atom's coordination geometry.
