i already have SF6. i need three more. also, are octahedrals polar or not?

PF6-, [PbCl6]2-, PCl6- are three others.
On whether they are polar or not, they are not IF the terminal atoms are all the same; instead, they are non-polar. If the terminal atoms are different, there is a chance they could be polar depending on the electronegativity of the atoms.

You have plenty of examples why only three.i can give you at least ten.few of them are( Ni(NH3)6)2+,K4(Fe(CN)6),(Fe(H20)6)3+,(Co(en)3)3+ where en=ethylene diamine a bi dented ligand.K3FeF6.Cr(CO)6,(Ni(H20)6)2+.Na4(Fe(CN)5NOS),
K3Co(CN)6,(Co(NH3)6)3+.If the molecules have a center of symmetry (a imaginary point in the molecule from which the distance of one group on one side is the same as from the other side ie if we start from one group reach to the point and extend equal distance in the opposite side then we arrive at the same group.)then it is nonpolar otherwise it is polar.

With octehedral you have 6 bonds and no lone pairs.
PCl6- and IF6+ are examples.
