For the molecule thionyl chloride (SOCl2), why is the shape trigonal pyramidal? Shouldn't the shape be T-shaped/trigonal bipyramidal?

S is attached to O via a double bond and attached to each Cl via a single bond. And since S has 6 valence electrons, it has one lone pair on itself, so the generic formula of SOCl2 is AX3E. Thus the shape is trigonal pyramidal.
