The mononuclear complex salt, [Cu(C3H5NS2)(C6H8N2S3)]NO3, contains a [C9H13CuN3S5]+cation and an NO3−anion. 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. The cationic complex adopts a slightly distorted trigonal–planar geometry about the CuIcation. In the crystal, layers parallel to (010) are generated by N—H...O hydrogen bonds, supported by short S...O [3.196 (4) and 3.038 (3) Å] and S...S contacts [3.4392 (13) Å]. Adjacent layers are linked by C—H...O hydrogen bonds and weak π–π stacking interactions [centroid–centroid distance = 4.0045 (10) Å] between the thiazoline rings, forming a three-dimensional network. This stacking also imposes a close contact, of approximately 3.678 Å, between the CuIcations and the centroids of the six-membered chelate rings of molecules in adjacent layers.

In the title complex, [Ag(NO3)(C5H5NO)]n, the AgIatom is coordinated by two O atoms from two different 4-pyridone ligands and two O atoms from one nitrate anion, displaying a nearly planar coordination geometry. The O atoms of two 4-pyridone ligands bridge two symmetrically related AgNO3units, forming a dimer, with an Ag...Ag separation of 3.680 (2) Å. Neighbouring dimers are linked into an infinite chain through weak Ag...O interactions [2.765 (2) Å], Ag...Ag interactions [3.1511 (4) Å] and π–π stacking interactions [centroid–centroid distance = 3.623 (4) Å]. N—H...O and C—H...O hydrogen bonds assemble these chains into a three-dimensional network.

In the title salt, C8H12NO+·NO3−, the 4-methoxybenzylammonium cation lies in the mirror planemof space groupPnmaand is thus planar by symmetry. The nitrate anion is also planar by symmetry, with an N...;O group in the mirror plane and one O atom in a general position. The dihedral angle between the benzene ring and the planar nitrate anion is constrained to be exactly 90°, because of the relative special positions for both ions. In the crystal, the cations are connected to the anions by C—H...O, C—H...N, N—H...N and N—H...O hydrogen bonds. Further, the crystal structure also features two C—H...π interactions involving the benzene ring of the cation, forming a three-dimensional network.

The Mn2+ion in (I) is coordinated by twoO,O′-bidentate Hspar neutral molecules (which exist as zwitterions) and anO,O′-bidentate bdc dianion to generate a distorted MnO6trigonal prism. A very long bond [2.580 (12) Å] from the Mn2+ion to a 0.25-occupied water molecule projects through a square face of the prism. In (II), the Cu2+ion lies on a crystallographic inversion centre and a CuO4square-planar geometry arises from its coordination by twoO,O′-bidentate Hspar molecules. The bdc dianion acts as a counter-ion to the cationic complex and does not bond to the metal ion. The Hspar ligands in both (I) and (II) feature intramolecular N—H...O hydrogen bonds, which closeS(6) rings. In the crystals of both (I) and (II), the components are linked by N—H...O, O—H...O and C—H...O hydrogen bonds, generating three-dimensional networks.
