ResumoSingle crystals of Dabco−MnGS−SB1 (MnGe4S10·(C6H14N2)·3H2O) were synthesized hydrothermally in the presence of Dabco (1,4-diazabicyclo[2.2.2]octane). This material (Pna21, a = 18.367(2), b = 14.184(2), and c = 9.410(1) Å) contains [Ge4S10]4- adamantine clusters corner-linked through distorted Mn2+ centers. The alternating Mn2+ centers and [Ge4S10]4- clusters lie at the nodes of a distorted Li-A(BW) net containing elliptical 8-rings. Channels defined by these 8-rings contain the template and water molecules. The distortion of S−Mn−S from the ideal tetrahedral angles is a result of the strain associated with ring system of the framework.
