Cl. Cahill et Jb. Parise, SYNTHESIS AND STRUCTURE OF MNGE4S10-CENTER-DOT(C6H14N2)CENTER-DOT-3H2O - A NOVEL SULFIDE FRAMEWORK ANALOGOUS TO ZEOLITE LI-A(BW), Chemistry of materials, 9(3), 1997, pp. 807-811
Single crystals of Dabco-MnGS-SB1 (MnGe4S10 (C6H14N2). 3H(2)O) were sy
nthesized hydrothermally in the presence of Dabco (1,4-diazabicyclo[2.
2.2]octane). This material (Pna2(1), a = 18.367(2), b = 14.184(2), and
c = 9.410(1) A) contains [Ge4S10](4-) adamantine clusters corner-link
ed through distorted Mn2+ centers. The alternating Mn2+ centers and [G
e4S10](4-) clusters Lie at the nodes of a distorted Li-A(BW) net conta
ining elliptical 8-rings. Channels defined by these 8-rings contain th
e template and water molecules. The distortion of S-Mn-S from the idea
l tetrahedral angles is a result of the strain associated with ring sy
stem of the framework.
