1,4,8,11-Tetra­azacyclo­tetra­decane anti­mony(III) sulfide

Poly[1,4,8,11-tetra­azacyclo­tetra­decane(2+) [hepta-μ-sulfido-tris­ulfidohexa­anti­mony(III)]], {(C₁₀H₂₆N₄)[Sb₆S₁₀]}_n, was synthesized solvothermally using the macrocyclic tetra­mine 1,4,8,11-tetra­azacyclo­tetra­decane (cyclam) as the structure-directing agent. The structure consists of novel [Sb₆S₁₀]²⁻ layers containing Sb₂S₂, Sb₄S₄ and Sb₇S₇ hetero-rings, which are separated by macrocyclic amine mol­ecules. The macrocylic amine mol­ecules are disordered over two crystallographically distinct positions and are diprotonated in order to balance the charge of the anionic layers.

catena-Poly[bis­(ethane-1,2-diammonium) [manganese(II)-di-μ-phosphato-κ⁴O:O′]]: a one-dimensional ­manganese phosphate

The title compound, {(C₂H₁₀N₂)₂[Mn(PO₄)₂]}_n, contains anionic square-twisted chains of formula [Mn(PO₄)₂]⁴⁻ constructed from corner-sharing four-membered rings of alternating MnO₄ and PO₄ units. The Mn and P atoms have distorted tetra­hedral coordination and the Mn atom lies on a twofold axis. The linear manganese–phosphate chains are held together by hydrogen-bonding interactions involving the framework O atoms and the H atoms of the ethane-1,2-diammonium cations, which lie in the inter­chain spaces.
