Synthesis and crystal structure of the one-dimensional infinite chain bismuth(III) complexes {Bi(NO₃)[S₂CN(C₄H₉)₂](CH₃OH)} ∞ and {Bi(NCS)[S₂CN(C₂H₅)₂]} ∞

Abstract

Synthesis of two novel bismuth(III) complexes with dithiocarbamate, {Bi(NO₃)[S₂CN(C₄H₉)₂](CH₃OH)} ∞ &nbsp;(<b>1</b>) and {Bi(NCS)[S₂CN(C₂H₅)₂]} ∞ (<b>2</b>) and determination of their crystal structures by X-ray single crystal diffraction are reported here. Crystal <b>1</b> belongs to triclinic with space group <i>P</i>₁<i>, a=</i>0.9563(3)<i> </i>nm, <i>b</i>=1.0333(4) nm, <i>c</i>=3.0599(11) nm, <i>α</i>=90.000(6)^o, <i>β</i>=90.000(7)^o; <i>γ=</i>90.771<i> </i>(7)^o; Z=4, V<i>=</i>3.0235(19) nm^-3, <i>D</i>c= 1.564 g/m³, <i>μ=</i>6.133<i> </i>mm^-1, <i>F</i>(000)<i>= </i>1416, <i>R</i>₁<i>=</i>0.0593<i> , </i>and <i>wR₂</i>=0.0864. Crystal <b>2</b> belongs to monoclinic with space group <i>P</i>2(1)/<i>n</i>, <i>a= </i>1.6142(3) nm, <i>b=</i>0.65713(14) nm, <i>c</i>= 1.8683(4) nm, <i>β=</i>111.098(4)^o; Z=4, V=1.8490(7) nm^-3 <i>Dc=</i>2.025<i> </i>g/m³, <i>μ=</i>10.094<i> </i>mm^-1, <i>F</i>(000)=<i> </i>1080, <i>R</i>₁<i>=</i>0.0383<i> , </i>and <i>wR</i>₂<i> </i>=0.0571. In complex <b>1</b>, the bismuth atoms exhibit seven-coordination in distorted pentagonal bipyramidal geometry by bridging nitrate O atoms resulting in one-dimensional infinite chain structure. In complex <b>2</b>, each bismuth atom adopts a distorted pentagonal bipyramidal geometry and the bridging thiocyanate groups link the Bi atoms to form one-dimensional chain polymer.
