We study the triple (G, π, .,.> ) where G is a connected and simply connected Lie group, π and .,.> are, respectively, a multiplicative Poisson tensor and a left invariant Riemannian metric on G such that the necessary conditions, introduced by Hawkins, to the existence of a non commutative deformation (in the direction of π) of the spectral triple associated to .,.> are satisfied. We show that the geometric problem of the classification of such triples (G, π, .,.> ) is equivalent to an algebraic one. We solve this algebraic problem in low dimensions and we give a list of all triples (G, π, .,.> ) satisfying Hawkins's conditions, up to dimension four.
