Abstract
The dinuclear title complex, [Mg2(C19H40N3Si2)2Cl2(C4H8O)2], lies on a center of inversion. The Mg2+ ions are bonded to a chelating N,N′-bonded guanidinate anion, a tetrahydrofuran molecule and two bridging chloride anions. The geometry of the resulting five-coordinated Mg2+ ion is a very distorted square-based pyramid with the O atom in the apical position.

Rigaku Saturn diffractometerR factor = 0.050; wR factor = 0.141; data-to-parameter ratio = 19.1
The Mg2+ ions are bonded to a chelating N,N0 -bonded guanidinate anion, a tetrahydrofuran molecule and two bridging chloride anions
The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
