The title compound, [Cu(C5H3N6)2(H2O)2]·2C5H3N3, is a 1:2 co-crystal between the mononuclear complex diaquabis[5-(pyrazin-2-yl)tetrazolato]copper(II) and the reagent pyrazine-2-carbonitrile which was used in the synthesis. The CuIIatom is located on an inversion centre and has a distorted octahedral [4 + 2]-coordination environment formed by four N atoms of two chelating bidentate 5-(pyrazin-2-yl)tetrazolate ligands at shorter distances and two water O atoms at longer distances. The CuIIcomplex molecules are held together by O—H...N hydrogen bonds and π–π stacking interactions [centroid–centroid distance 3.6139 (8) Å], forming layers parallel to (100). These layers alternate with layers of pyrazine-2-carbonitrile molecules and both are held togetherviaC—H...N hydrogen bonds and further π–π stacking interactions.

Cl Atom

The asymmetric unit of the title compound, [ReCl(C5H5NO)2(CO)3]·C5H5NO, contains one molecule of the complexfac-[ReCl(4-pyOH)2(CO)3] (where 4-pyOH represents 4-hydroxypyridine) and one molecule of pyridin-4(1H)-one (4-HpyO). In the molecule of the complex, the Re atom is coordinated to two N atoms of the two 4-pyOH ligands, three carbonyl C atoms, in a facial configuration, and the Cl atom. The resulting geometry is slightly distorted octahedral. In the crystal structure, both fragments are associated by hydrogen bonds; two 4-HpyO molecules bridge between two molecules of the complex using the O=C group as acceptor for two different HO– groups of coordinated 4-pyOH from two neighbouring metal complexes. The resulting square arrangements are extented into infinite chains by hydrogen bonds involving the N—H groups of the 4-HpyO molecule and the chloride ligands. The chains are further stabilized by π-stacking interactions.
