Three-centre hydrogen bonds in triphenylphosphine oxide–hydroquinone (1/1)
نویسندگان
چکیده
The title cocrystal, C(18)H(15)OP·C(6)H(6)O(2), belongs to a series of mol-ecular systems based on triphenyl-phosphine P-oxide. The O atom of the oxide group acts as an acceptor for hydrogen bonds from OH groups of two hydro-quinone mol-ecules which lie on inversion centres [O⋯O = 2.7451 (17) and 2.681 (2) Å]. The crystal structure is stabilized by weak C-H⋯O hydrogen bonds, forming a C(2) (1)(8) chain which runs parallel to the [100] direction.

In the salt, (H(3)O)(2)[Cd(2)Br(4.5)Cl(1.5)]·6C(18)H(15)OP, the hydro-nium cation forms short O-H⋯O hydrogen bonds to the O atoms of the triphenyl-phosphine oxide units. The centrosymmetric dinuclear anion has two halide atoms functioning in a bridging mode, which confers tetra-hedral coordination to the Cd atom. The three independent halide atoms are each a mixture of bromide and chloride; the...
