Di-μ-chlorido-bis­{bis­[4-(adamantan-1-ylcarbamo­yl)pyridine-κN]chlorido­copper(II)} hemihydrate

In the centrosymmetric dimeric title compound, [Cu(2)Cl(4)(C(16)H(20)N(2)O)(4)]·0.5H(2)O, the Cu(II) atom is in a distorted trigonal–bipyramidal environment defined by two bridging Cl atoms, one terminal Cl atom and two N atoms from two monodentate 4-(adamantan-1-ylcarbamo­yl)pyridine ligands. The amine N atoms are involved in intra­molecular N—H⋯O and inter­molecular N—H⋯Cl hydrogen bonds. The latter hydrogen bonds link the complex mol­ecules into a ribbon along [010]. The uncoordinated water mol­ecule is 0.25-occupied.
