Description
Summary:On allowing (Cy2NH2)2C2O4∙2H2O to react with SnBu3Cl or SnMe3Cl, i-Bu2NH2HC2O4 with SnBu3Cl, (Bu2NH2)2C2O4 with SnMe3Cl, (i-Bu2NH2)2C2O4 with SnPh2Cl2, a mixture of i-Bu2NH2)2C2O4 and (Me4N)2C2O4 with SnPh2Cl2, (Pr2NH2)2C2O4 with SnPh3Cl, the oxalato derivatives and complexes Cy2NH2C2O4SnBu3.3H2O∙1/4Cy2NH2Cl, i-Bu2NH2C2O4SnBu3∙1/2(i-Bu2NH2)2C2O4,y2NH2C2O4SnMe3∙1/2(Cy2NH2)2C2O4, Sn(C2O4)2∙[C2O4(SnMe3∙H2O)2]∙2EtOH∙1/4[(Bu2NH2)2C2O4],(i-Bu2NH2)2 C2O4∙ 2SnPh2Cl2∙SnCl4∙4(i-Bu2NH2OH)∙2(i-Bu2NH2Cl), 2[SnPh2Cl4(i-Bu2NH2)2]∙ SnCl2C2O4∙4i-Bu2NH2Cl and 2[Pr2NH2C2O4SnPh3]∙(Pr2NH2)2C2O4∙SnCl4∙ 2Pr2NH2Cl were obtained. Double chain, two metallic components and a dimeric structures are suggested with trans coordinated SnMe3 residues, these chains being connected through R2NH2+ (R = Cy, i-Bu) only or by (R2NH2)2C2O4 bridges. The oxalate behaves as a monochelating, a bridging, an only hydrogen bonding involved or monodentate and H bond involved ligand. The environments around the tin (IV) centres are cis or trans trigonal bipyramidal, tetrahedral or octahedral. Supramolecular architectures may be obtained when extra hydrogen bonds are possible.
