Crystal structures of three complexes of zinc chloride with tri-tert-butylphosphane

Abstract

The crystal structures of three complexes of zinc chloride with tri-tert-butyl­phosphane are reported.

Synthesis, characterization and catalytic activities of Zn(II) and Cd(II) complexes supported by unsymmetrical aryl thiourea ligands

“…The molecular structures of complexes 1 – 8 appear to be isostructural. The zinc‐halide bond distance in complex 1 is [Zn1−Cl1 2.250(2) and Zn1−Cl2 2.246(2) Å], which is observed to be in agreement with Zn−Cl bond length from the previous report describing the formation of the metal complex [21] . Similar bond lengths, [Zn1−Cl1 2.2416(17) and Zn1−Cl1i 2.2416(17) Å], were noted for complex 5 .…”

“…The zinc-halide bond distance in complex 1 is [Zn1À Cl1 2.250(2) and Zn1À Cl2 2.246(2) Å], which is observed to be in agreement with ZnÀ Cl bond length from the previous report describing the formation of the metal complex. [21] Similar bond lengths, [Zn1À Cl1 2.2416(17) and Zn1À Cl1i 2.2416( 17) Å], were noted for complex 5. Likewise, the ZnÀ Br bond lengths, namely [Zn1À Br1 2.3612 (11) and Zn1À Br2 2.3637 (11) Å] in complex 2, [Zn1À Br1 2.3887(8) and Zn1À Br1i 2.3886(8) Å] in complex 6 and [Zn1À Br1 2.3848(13); and the ZnÀ I bond lengths [Zn1À I2 2.5835(8) and Zn1À I2i 2.5835(8) Å] in complex 7 are also in good agreement with other tetrahedral zinc(II) complexes and thus suggest the bent geometry of the bromide and iodide groups around the metal center forming the four-fold coordination.…”
