The Sn^IV atom in the centrosymmetric title complex, [Sn₂(CH₃)₄(NCS)₂(OH)₂], adopts a distorted trigonal-bipyramidal coordination environment defined by two methyl C atoms and one bridging hydroxide group in the equatorial plane while the other bridging hydroxide group and the N atom of the thiocyanate anion are in the apical >positions. The dinuclear species are linked through O-HS and C-H S hydrogen-bonding interactions into a three-dimensional network.
