摘　　要：The novel complex di-n-butyltin(IV) 2-oxo-propionic acid (4-pyridinecarbonyl) hydrazone, (n-C4H9)2Sn- [O2CC(CH3)=N—N=C(—O)C5H4N-4]·(H2O) has been synthesized and its structure has been determined by X-ray diffraction analysis. The complex crystallizes in orthorhombic system with space group Pca21. Crystal data: a=2.7540(9) nm, b=0.9676(3) nm, c=1.5750(5) nm, V=4.197(2) nm3, Dc=1.444 g/cm3, Z=8, =1.241 mm1, F(000)=1856, R1=0.0462 and wR2=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) form-ing 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.The novel complex di-n-butyltin(IV) 2-oxo-propionic acid (4-pyridinecarbonyl) hydrazone, (n-C4H9)2Sn- [O2CC(CH3)=N—N=C(—O)C5H4N-4]·(H2O) has been synthesized and its structure has been determined by X-ray diffraction analysis.
