metal-organic compounds
The asymmetric unit of the title compound, di-μ-aqua-1:2κ4O:O-triaqua-1κ3O-dilosartanido-1κN;2κ2N,N′-dipotassium dihydrate, [K2(C22H22ClN6O)2(H2O)5]·2H2O, is composed of two losartan anions, two K+ cations and seven water molecules. Some water molecules bridge the potassium ions linking the molecules to form an infinite chain. The two potassium ions have different environments; one is six-coordinated by three water O atoms and three tetrazole N atoms, whereas the other is five-coordinated by five water O atoms. Extensive hydrogen-bonding interactions lead to a three-dimensional structure.
