4-(24-Dichloro­phen­yl)-55-dimethyl-2-(3-silatranyl­propyl­mino)-132-dioxa­phospho­rinane 2-oxide

摘要

In the title compound, C20H31Cl2N2O6PSi, the dioxaphospho­rinane ring adopts a cis conformation. The silatrane fragment forms a cage-like structure in which there exists an intra­molecular Si—N donor–acceptor bond. In the crystal, centrosymmetrically related mol­ecules 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 inter­molecular C—H⋯O hydrogen bonds.
