The title structures, [M(C6H12NOS2)2(C10H8N2)]·0.5C10H8N2, for M = Zn, (I), and Cd, (II), feature terminally bound 4,4′-bipyridyl ligands and non-coordinating 4,4′-bi­pyridyl mol­ecules, with the latter disposed about a centre of inversion. The coordination geometry about the metal atom is defined by two non-symmetrically chelating di­thio­carbamate ligands and a pyridyl N atom. The NS4 donor sets are distorted but, approximate to trigonal bipyramidal in each case. In the crystal, hy­droxy-O—H...O(hy­droxy) and hy­droxy-O—H...N(pyrid­yl) hydrogen bonds between the zinc-containing mol­ecules lead to a supra­molecular layer parallel to (100). The three-dimensional architecture arises as the layers are linked via methine-C—H...S, pyridyl-C—H...O(hy­droxy) and π–π [inter-centroid distance between coordinated pyridyl rings = 3.6246 (18) Å] inter­actions. Channels along the c-axis direction are occupied by the non-coordinating 4,4′-bipyridine mol­ecules, which are held in place by C—H...π(chelate ring) contacts.
