In the title compound, [Sn(C7H14O5P) (C6H5)(3)], the planar triphenylt
in cations are axially bridged through the carboxy and phosphoryl O at
oms of the 3-(diethylphosphono)propionate anions into zigzag chains th
at run parallel to the c axis {i.e. yltin-mu-3-(diethylphosphono)propi
onato-O:O-P=O]}.
