Synthesis and Structure of MnGe₄S₁₀·(C₆H₁₄N₂)·3H₂O: A Novel Sulfide Framework Analogous to Zeolite Li-A(BW)

Single crystals of Dabco−MnGS−SB1 (MnGe 4 S 10 ·(C 6 H 14 N 2 )·3H 2 O) were synthesized hydrothermally in the presence of Dabco (1,4-diazabicyclo[2.2.2]octane). This material ( Pna 2 1, a = 18.367(2), b = 14.184(2), and c = 9.410(1) Å) contains [Ge 4 S 10 ] 4 - adamantine clusters corner-linked through distorted Mn 2+ centers. The alternating Mn 2+ centers and [Ge 4 S 10 ] 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.
