title: Tetra-ethyl-ammonium tricarbonyl-chlorido(isoquinoline-1-carboxyl-ato-κN,O)technetate(I).
abstract: The asymmetric unit of the title compound, (C(8)H(20)N)[Tc(C(10)H(6)NO(2))Cl(CO)(3)], consists of two crystallographically independent technetium complexes related via a pseudo-inversion centre and two tetra-ethyl-ammonium cations. The Tc atoms have slightly distorted octa-hedral coordination geometries, and they are linked with the cations by inter-molecular C-H⋯O and C-H⋯Cl hydrogen-bonding contacts, forming two-dimensional columns, which lie approximately parallel to (001) in the crystal structure. The isochinolate (isoquinoline-1-carboxyl-ate) ligands link the columns by partial π-π stacking [centroid-centroid distance 4.3733 (11) Å], forming a three-dimensional network structure.
