	Article:	A NOVEL DISILOXANEDIOLATO - DERIVATIVE OF TIN(IV). Authors: PETRONELA M. PETRAR, GABRIELA CRETIU NEMES, IOAN SILAGHI-DUMITRESCU.


	Abstract: Bis[�2 (bis(tetrahydrofuran) lithium(tetraphenyl-disiloxane 1,5 diolato)] dimethyltin (IV) (1) has been obtained from the reaction of diphenylsilanediol with butylithium and dimethyltin dichloride. The crystal of (1) is monoclinic, space group P2(1)/n with the unit cell dimensions: a = 10.4609(9) �, b = 19.9896(16) �, c = 17.9295(15) �,  = 90.00o,  = 105.791(2),  = 90.00. The tin atom has a slightly distorted octahedral environment. The silandiol ligands coordinate also two lithium atoms forming thus two planar LiO2Sn chelate rings.
