What is the shape of sf4 (including bond angles)?
Answers:
The axial F-S-F angles is 173 degrees and the equatorial F-S-F angle is 101.4 degrees.
The sites below has a good diagrams and additional information:
It looks a bit like a seesaw.
There's a picture here:
Structure of sulfur tetrafluoride, SF4
it contains 34 electrons.

SF4 3s23p4 dsp3 irregular tetrahedral
SF4 has bond angles of 179 and 103 degrees
It's described as distorted tetrahedral or "sawhorse" shape. If you want to know how to work it out, try this.
S is in group 6 so has 6 valence electrons.in SF4 there are 4 bonds, so 4 of the valence elctrons from S are used in bonding. That means that 2 of them are not, so exist as a lone pair. That's 5 pairs of electrons (4 bond pairs and a lone pair) round the S atom. So SF4 is based on a trigonal bipyramidal structure, but because there is a lone pair, that lone pair will repel the 4 bond pairs somewhat, thereby distorting the shape from TBP to sawhorse. Angles are as other answers have said.
