Structural variations of Sn-II pyridylphosphonates influenced by an uncommon Sn-N interaction Academic Article uri icon


  • 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) , b=10.7673(18) , c=13.996(2) , and =93.616(2). Tri-tin(II) (-3)-oxo-(bis)-4-pyridylphosphonate, Sn3O(O3PC5H4N)2 (II), crystallizes in P-1 with a=7.2406(14) , b=9.9524(19) , c=12.604(3) , =104.510(11), =90.326(11), and =110.897(11). Tin(II) 6-methyl-2-pyridylphosphonate quadrahydrate, Sn(O3PC5H3NCH3)0.25H2O (III), crystallizes in Pna21, a=18.955(3) , b=9.7543(14) , and c=17.833(3) . Tin(II) 4-cyanophenylphosphonate, Sn(O3PC6H4CN) (IV), crystallizes in P-1, a=5.0019(3) , b=8.4396(5) , c=10.3099(6) , =90.352(3), =94.894(3), and =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. 2010 Elsevier Inc.
