Abstract: From the reaction of copper(II) chloride dihydrate with N 1 , N 1 -dimethyl- N 2 -(pyridin-2-ylmethyl)ethane-1,2-diamine (denoted N^N^N) a new species comprising three distinct complexes crystallized, namely, aquachlorido[ N 1 , N 1 -dimethyl- N 2 -(pyridin-2-ylmethyl)ethane-1,2-diamine-κ 3 N , N ′, N ′′]copper(II) chlorido[ N 1 , N 1 -dimethyl- N 2 -(pyridin-2-ylmethyl)ethane-1,2-diamine-κ 3 N , N ′, N ′′]copper(II) tetrachloridocuprate(II), [CuCl(C 10 H 17 N 3 )(H 2 O)][CuCl(C 10 H 17 N 3 )][CuCl 4 ] or [Cu(N^N^N)(H 2 O)Cl][Cu(N^N^N)Cl 2 ][CuCl 4 ], the latter two of which form an adduct. This complex was reacted with ammonium thiocyanate to form [Cu(N^N^N)(NCS) 2 ], which crystallized with two independent molecules and a partial water in the asymmetric unit very similarly to the already reported structure of this compound. Both crystal structures show a rather complex set of intermolecular interactions including hydrogen bonding and what may be described as chalcogen bonding, pnictogen bonding and/or coinage bonding. The molecular structures, intramolecular interactions and packing patterns are discussed in detail and the more unusual ones are set into the context of structures available in the literature.
