title: 1,4,8,11-Tetraazoniacyclotetradecane tetrakis(phenylphosphonate) dihydrate forms hydrogen-bonded sheets.
abstract: In the title compound, C(10)H(28)N(4)(4+).4C(6)H(6)O(3)P(-).2H(2)O, the cation lies across a centre of inversion in space group P2(1)/n. The two independent anions and the water molecule are linked by four O-H.O hydrogen bonds [H.O = 1.74-2.15 (3) A, O.O = 2.5482 (14)-3.0438 (16) A and O-H.O = 160-176 (2) degrees ] into sheets containing equal numbers of centrosymmetric R(6)(6)(16) and R(10)(10)(36) rings. The cation lies at the centre of the R(10)(10)(36) ring and is linked to it by eight N-H.O hydrogen bonds [H.O = 1.77-1.98 A, N.O = 2.6756 (15)-2.8168 (16) A and N-H.O = 151-169 degrees ].
