The title compound, [BaCl(2)(C(2)H(6)SO)], forms a Ba(6)Cl(9) cluster in which the BaCl(2) units are connected via dimethyl-sulfoxide (DMSO) and chloride bridges. The central Cl atom of the Ba(6)Cl(9) cluster is located on a threefold inversion axis and is coordinated octa-hedrally to six barium cations. In the crystal, the clusters are arranged in rows, which are inter-connected by the DMSO mol-ecules, forming a three-dimensional network.

The title compound, [Cu(C(12)H(8)N(2))(C(18)H(15)P)(2)](2)[Mo(6)O(19)], was obtained by co-crystallization of the mixed-ligand copper complex cation (1,10-phenanthroline)bis-(triphenyl-phos-phane)copper(I), [Cu(phen)(PPh(3))(2)](+), with the Lindquist polyanion [Mo(6)O(19)](2-). The asymmetric unit consists of half a Lindquist anion and one [Cu(phen)(PPh(3))(2)](+) cationic complex. In the cation, there are intra-molecular π-π inter-actions [centroid-centroid distances = 3.617 (2) and 3.7272 (18) Å]. This inorganic-organic adduct is connected by C-H⋯O hydrogen bonds, forming a two dimensional network lying in the ab plane. These networks are connected by C-H⋯π inter-actions into a three-dimensional structure.

The title compound, (C(6)H(9)N(2))(2)[Cu(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O, consists of a mononuclear trans-[Cu(pzdc)(2)(H(2)O)(2)](2-) dianion (pzdc is pyrazine-2,3-dicarboxyl-ate) and two [ampyH](+) cations (ampy is 2-amino-4-methyl-pyridine) with six water mol-ecules of solvation. The Cu(II) atom is hexa-coordinated by two pzdc groups and two water mol-ecules. The coordinated water mol-ecules are in trans-diaxial positions and the pzdc dianion acts as a bidentate ligand through an O atom of the carboxyl-ate group and the N atom of the pyrazine ring. There are diverse hydrogen-bonding inter-actions, such as N-H⋯O and O-H⋯O contacts, which lead to the formation of a three-dimensional supra-molecular architecture.
