title: 1-Hydr-oxy-1,1,3,3,3-penta-phenyl-disiloxane, [Si(2)O(OH)(Ph)(5)], at 100 K.
abstract: In the crystal structure of the title compound, C(30)H(26)O(2)Si(2), one Si(Ph)(3) residue is bound to another Si(OH)(Ph)(2) residue via a non-linear Si-O-Si bridge. The asymmetric unit is composed of two such molecules which inter-act, on the one hand, via a strong and highly directional O-H⋯O hydrogen bond involving the two neighbouring Si-OH units and, on the other, via an O-H⋯π contact connecting the second hydroxyl group with an adjacent phenyl group.
