The C3-symmetrical molecule, tris(4-methoxyphenyl)stibine, C21H21O3Sb, crystallizes with one third of the molecule in the asymmetric unit. Bond lengths and angles of the Sb—C bonds lie in between those of the isostructural homologues C21H21O3Bi and C21H21O3As. The formation of dimers via six weak C—H...π interactions is considered.
