Synthesis and Crystal Structure of Di‐ n ‐butyltin(IV) Complex with 2‐Oxo‐propionic Acid (4‐Pyridinecarbonyl) Hydrazone

The novel complex di‐ n ‐butyltin(IV) 2‐oxo‐propionic acid (4‐pyridinecarbonyl) hydrazone, ( n‐ C 4 H 9 ) 2 Sn‐[O 2 CC(CH 3 )=N‐N=C(‐O)C 5 N‐4] (H 2 O) has been synthesized and its structure has been determined by X‐ray diffraction analysis. The complex crystallizes in orthorhombic system with space group Pca2 1 . Crystal data: a =2.7540(9) nm, b =0.9676(3) nm, c= 1.5750(5) nm, V=4.197(2) nm 3 , D c = 1.444 g/cm 3 , Z=8. μ= 1.241 mm −1 . F (000)= 1856, R 1 =0.0462 and wR 2 =0.1001 . In the crystals of the title complex, the tin atom is in six‐coordination with a distorted octahedral geometry, three oxygen atoms [O(1), O(3) and O(4)] and one nitrogen atom N(1) forming the equatorial plane and C(10)‐Sn(1)‐C(14) being the axis. Two molecules form a dimer with weak interactions of Sn‐O bonding and hydrogen bonds.
