fac-[Re(CO)3(κ2-N,N-dpktah)Cl] confirmed its identity and divulge two symmetry-independent molecules in the asymmetric unit. The supramolecular structure of fac-[Re(CO)3(κ2-N,N-dpktah)Cl] disclosed anti-parallel chains locked via a network of hydrogen bonds. Non-classic hydrogen bonds of the type C–H…Cl connect molecules in the chain and classic hydrogen bonds of the type N–H…O connect adjacent chains.
