Structural variations of SnII pyridylphosphonates influenced by an uncommon Sn–N interaction
چکیده انگلیسی

Four new SnII phosphonates have been synthesized by hydrothermal methods, and their structures determined by single-crystal X-ray diffraction. Tin(II) 3-pyridylphosphonate, SnO3PC5H4N (I), crystallizes in P21/c with a=4.9595(8) Å, b=10.7673(18) Å, c=13.996(2) Å, and β=93.616(2)°. Tri-tin(II) (μ-3)-oxo-(bis)-4-pyridylphosphonate, Sn3O(O3PC5H4N)2 (II), crystallizes in P-1 with a=7.2406(14) Å, b=9.9524(19) Å, c=12.604(3) Å, α=104.510(11)°, β=90.326(11)°, and γ=110.897(11)°. Tin(II) 6-methyl-2-pyridylphosphonate quadrahydrate, Sn(O3PC5H3NCH3)·0.25H2O (III), crystallizes in Pna21, a=18.955(3) Å, b=9.7543(14) Å, and c=17.833(3) Å. Tin(II) 4-cyanophenylphosphonate, Sn(O3PC6H4CN) (IV), crystallizes in P-1, a=5.0019(3) Å, b=8.4396(5) Å, c=10.3099(6) Å, α=90.352(3)°, β=94.894(3)°, and γ=92.236(4)°. I, II, and IV have ladder-type structures, and III is a layered compound. The structural variations show the effects of the Sn–N interaction on the final structures.

Interactions between pyridyl nitrogen atoms and SnII affect the packing of tin phosphonate ladders in the structures of SnII pyridylphosphonates.Figure optionsDownload as PowerPoint slide
