The structure of rubidium gadolinium bis(tungstate), RbGd(WO4)2, has been determined. The crystal is built up from corner- and edge-sharing WO6 octahedral and GdO8 polyhedral groups, giving rise to a Gd-WO4 polyhedral backbone surrounding structural cavities filled with Rb+ cations. The Gd and Rb atoms lie on twofold axes.
The title complex, [MnHg(NCS)4(C2H5NO)2]n, consists of slightly distorted MnN4O2 octahedra and HgS4 tetrahedra. Each Mn(II) cation is bound to four N atoms of the NCS groups and two O atoms of the N-methylformamide (NMF) ligands in a cis configuration. Each Hg(II) cation is coordinated to four S atoms of NCS groups. Each pair of Mn(II) and Hg(II) cations is connected by an -NCS- bridge, forming an infinite three-dimensional -Mn-NCS-Hg- network.
The title complex, [[CdHg(SCN)(4)(C(4)H(9)NO)(2)](2)](n), contains two crystallographically independent Cd(II) centres and two Hg(II) centres. Each Cd(II) atom is bound to four N atoms belonging to SCN groups and to two O atoms from N,N-dimethylacetamide (DMA) ligands in an octahedral geometry. Each Hg(II) centre is tetrahedrally coordinated by four SCN S atoms.
The Cd(II) ion in the title complex, [Cd(SCN)(2)[SC(NH(2))(2)](2)](infinity), is situated at a centre of symmetry, and is bound to two N atoms belonging to thiocyanate groups and to four S atoms of bridging thiourea ligands. The structure consists of infinite chains of slightly distorted edge-shared Cd-centred octahedra. The bridging S atoms of two thiourea ligands comprise the common edge. Some thermal properties are described.
In the title compound, Bi(2)B(8)O(15), the Bi atom is coordinated to five or six O atoms. The B atoms exhibit two kinds of hybridization, sp(2) and sp(3), seen in the BO(3) triangles and BO(4) tetrahedra, respectively. Three BO(3) triangles are connected to form a B(3)O(6) planar ring. All atoms in the structure are connected together to form an infinite three-dimensional network.
The title complex, [MnHg(SCN)4(CH4N2O)3]n, consists of slightly distorted octahedral MnN3O3 and tetrahedral HgS4 units. The Mn(II) atom is coordinated by the O atoms of three urea molecules and by the N atoms of three SCN- ions; Hg(II) is coordinated by four S atoms from SCN- ions. Each pair of Mn(II) and Hg(II) atoms is connected by an -SCN- bridge, forming infinite two-dimensional -Mn-NCS-Hg- networks.
