In  Salce introduced the notion of a co-torsion pair (A, B) in the category of abelian groups. But his deﬁnitions and basic results carry over to more general abelian categories and have proved useful in a variety of settings. In this article we will consider complete cotorsion pairs (C, D)in the category C(R-Mod) of complexes of left R-modules over some ring R.If(C, D) is such a pair, and if C is closed un-der taking suspensions, we will show when we regard K(C) and K(D) as subcategories of the homotopy category K(R-Mod), then the embedding functors K(C) → K(R-Mod) and K(D) → K(R-Mod) have left and right adjoints, respectively. In ﬁnding examples of such pairs, we will describe a procedure for using Hoveys results in  to ﬁnd a new model structure on C(R-Mod).
