Is TeF4 a tetrahedral

Answer 1

There are two answers to this question, depending on the physical state of the TeF4

The solid is a network compound with a sp3d2 (slightly distorted octahedral) co-ordination about each Te atom.

The isolated molecule -- low pressure vapour -- has sp2-pd co-ordination.

s, px, & py combine to make a trigonal planar co-ordination with two slots occupied by Te-F bonds and the third has a non-bonding lone pair.

At somewhat lower binding energy, pz & dz2 orbitals combine to make the other two Te-F bonds.

Answer 2

Trigonal Bipyramidal

Answer 3

TTRAHEDRAL
