Intermolecular coordination, pseudo-octahedral

NiBr 3>0 C9H4O C(C2H5>=N CH2CH2N(CH3)2 brown ) room 1.67 Farad pseudo-octahedral coordination suggested due to intermolecular association 74D19... 

By taking into account the secondary interactions, for structural types (S and T) and (V and W) the coordination geometry at the metal center is pseudo-octahedral, and in (U) and (X), square-based pyramidal. The intramolecular copper-sulfur bonds of 2.2 A are some 0.1 A shorter than those in [Cu(S2CNR2)2], although the intermolecular copper-sulfur interactions are considerably longer (3.1-3.7 A as compared with 2.7-2.9 A).
