Dicyclo-hexyl-ammonium trimethyl-bis-(hydrogen phenyl-phospho-nato)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⋯O hydrogen bonds involving the hy-droxy group of the hydrogen phenyl-phospho-nate ion. The chains inter-act with one another via O-H⋯O hydrogen bonds along the c axis. These networks of anions assemble with the dicyclo-hexyl-ammonium ion through N-H⋯O hydrogen bonds, forming a three-dimensional network.
