In the mononuclear complex title salt, all of the non-H atoms of the cation lie on a mirror plane, as do the N and one O atom of the nitrate anion, such that the planes of the cation and anion are mutually orthogonal. In the crystal, layers parallel to (010) are generated by N—HO hydrogen bonds, supported by short SO [3.196 (4) and 3.038 (3) Å] and SS contacts [3.4392 (13) Å].

{[Fe(H2O)2{Ag(CN)2}2](2,2′-bpe)2}n forms a two-dimensional grid-type structure with the organic guest molecules occupying the space between adjacent grid layers. The grid layers are held together by hydrogen bonds between the organic guest molecules and the host framework and gives rise to a three-dimensional supramolecular architecture.

The asymmetric unit of the title compound, [Co2(NCS)4(C10H8N2)3(C2H6OS)2]n, consists of one CoII atom, two thiocyanate anions, one dimethyl sulfoxide molecule and one and a half 4,4′-bipyridine molecules. The half-molecule is completed by inversion symmetry. The CoII atom is coordinated in a distorted octahedral geometry by two N atoms from two thiocyanate anions, one O atom from dimethyl sulfoxide as a terminal ligand and three N atoms from three 4,4′-bipyridine molecules as bridging ligands linking the cations, with a CoCo separation of 11.5964 (5) Å. This generates a two-dimensional structure parallel to (-103). A C—HS hydrogen bond links the layers into a three-dimensional supramolecular framework. The layers are stacked in an ABC fashion preventing the occurrence of interlayer void space and hence leading to the absence of lattice solvent and/or organic guest molecules in the structure.

In the title salt, [Ag(C7H8N2S)(C18H15P)2]NO3, the coordination geometry about the AgI atom is shallow trigonal pyramidal, with the metal atom displaced by 0.372 (1) Å from the plane of the P and S atoms. In the crystal, the cations are linked to the anions by N—HO hydrogen bonds, generating tetramers (two cations and two anions), which feature R22(8) and R44(8) loops. The cations are linked by weak C—Hπ interactions, generating a three-dimensional network.
