Notes:
catena-Poly[dicyclohexylammonium [tributyltin-μ-(4-oxo-4H-pyran-2,6-dicarboxylato-O2:O6)]], (C12H24N)[Sn(C7H2O6)(C4H9)3], consists of 4-oxo-4H-pyran-2,6-dicarboxylato groups that axially link adjacent tributyltin units into a linear polyanionic chain. The ammonium counter-ions surround the chain, and each cation forms a pair of hydrogen bonds to the double-bond carbonyl O atoms of the same dianionic group. The chain propagates in a zigzag manner along the c axis of the monoclinic cell. In catena-poly[methyl(phenyl)ammonium [tributyltin-μ-(pyridine-2,6-dicarboxylato-O2:O6)]], (C7H10N)[Sn(C7H3NO4)(C4H9)3], the pyridine-2,6-dicarboxylato groups also link the tributyltin groups into a chain, but the hydrogen-bonded chain propagates linearly on the ac face of the monoclinic cell.
