Dicyclohexylammonium trimethylbis(hydrogen phenylphosphonato)stannate(IV)

In the title compound, (C(12)H(24)N)[Sn(CH(3))(3)(C(6)H(6)O(3)P)(2)], the SnMe(3) residues are axially coordinated by two monodentate [PhPO(3)H](-) anions, leading to a trigonal-bipyramidal geometry for the Sn(IV) atom. The two [SnMe(3)(PhPO(3)H)(2)](-) anions in the unit cell are associated into infinite chains along the a axis by O-H center dot center dot center dot O hydrogen bonds involving the hydroxy group of the hydrogen phenylphosphonate ion. The chains interact with one another via O-H center dot center dot center dot O hydrogen bonds along the c axis. These networks of anions assemble with the dicyclohexylammonium ion through N-H center dot center dot center dot O hydrogen bonds, forming a three-dimensional network.
