Abstract
The structure of the title compound, SnMe2Cl2(dmp)2, has been determined by a single-crystal X-ray techniques using diffractometer data. The compound crystallizes in the monoclinic space group C2/c with four molecules in a cell of dimensions a= 13.62(1), b= 10.42(1), c= 12.34(1)Å, and β= 92.76(5)°. Least-squares refinement of the structure has led to a final R value of 0.045 using 1 122 observed intensities. The complex consists of discrete trans-SnMe2Cl2(dmp)2 units held together by intermolecular Cl H bonds to form infinite linear chains along the c axis. The tin and the metal-bonded methyl carbon atoms lie on a crystallographic two-fold axis of symmetry. The 3,5-dimethylpyrazole ligands are bonded to the metal through their pyridine-like nitrogen atom. The Sn–C, Sn–Cl, and Sn–N bond distances are 2.11 (1), 2.581(2), and 2.379(6)Å respectively.Keywords
