title: 4-(2,4-Dichloro-phen-yl)-5,5-dimethyl-2-(3-silatranyl-propyl-mino)-1,3,2-dioxa-phospho-rinane 2-oxide.
abstract: In the title compound, C(20)H(31)Cl(2)N(2)O(6)PSi, the dioxaphospho-rinane ring adopts a cis conformation. The silatrane fragment forms a cage-like structure in which there exists an intra-molecular Si-N donor-acceptor bond. In the crystal, centrosymmetrically related mol-ecules are linked by pairs of N-H⋯O hydrogen bonds into inversion dimers, generating rings with graph-set motif R(2) (2)(8). The dimers are further connected into ribbons parallel to the a axis by inter-molecular C-H⋯O hydrogen bonds.
