Three new dimethyltin complexes of N-(3-methoxysalicylidene)-α-amino acid,(CH3)2Sn(3-CH3O-2-OC6H3CH=NCHRCOO)(R = H,1;CH3,2;(CH3)2CH,3),have been synthe-sized by treating dimethyltin dichloride with the potassium salt of the ligand and characterized by elemental analysis,IR and 1H NMR spectra.The crystal structure of [(CH3)2Sn(3-CH3O-2-OC6H3CH=NCH2COO)(CH3OH)]2 H2O(1a),formed from methanol solution of 1,has been deter-mined.The crystal belongs to the monoclinic system,space group C/2c with a = 20.636(3),b = 7.8854(9),c = 20.668(2) ,β= 113.265(2)°,V = 3089.7(6) 3,Z = 4,Dc = 1.707 g/cm3,= 1.675 mm-1,F(000) = 1592,R = 0.0301 and wR = 0.0841.In complex 1a,the tin atom is six-coordinate and possesses a distorted [SnC2NO3] octahedral geometry with the two methyl groups occupying the trans positions.The weak Sn O interactions and intermolecular hydrogen bonds connected the molecules into an infinite chain.
Three new dimethyltin complexes of N- (3-methoxysalicylidene) -alpha-amino acid (CH3) 2Sn (3-CH3O-2-OC6H3CH = NCHRCOO) ), have been synthe-sized by treating dimethyltin dichloride with the potassium salt of the ligand and characterized by elemental analysis, IR and 1H NMR spectra. crystal structure of [(CH3) 2Sn (3-CH3O-2-OC6H3CH = NCH2COO) (CH3OH) 2 H2O (1a), formed from methanol solution of 1, has been deter mined. The crystal belongs to the monoclinic system, space group C / 2c with a = 20.636 (3), b = 7.8854 (9) , C = 20.668 (2) β, β = 113.265 (2) °, V = 3089.7 (6) 3, Z = 4, Dc = 1.707 g / cm3, = 1.675 mm- R = 0.0301 and wR = 0.0841. In complex 1a, the tin atom is six-coordinate and possesses a distorted [SnC2NO3] octahedral geometry with the two methyl groups occupying the trans positions. The weak Sn O interactions and intermolecular hydrogen bonds connected the molecules into an infinite chain
