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, μ＝1.241 mm-1, 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) 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.
