A crystal 0.250 mm x 0.100 mm x 0.075 mm in size was selected, mounted on a nylon loop with Paratone-N oil, and transferred to a Bruker SMART APEX diffractometer equipped with an Oxford Cryosystems 600 Series Cryostream Cooler and Mo K\a radiation (\l = 0.71073 \%A). A total of 3840 frames were collected at 193(2) K to \q~max~ = 27.5\% with an oscillation range of 0.3\%/frame, and an exposure time of 10 s/frame using SMART software. (Bruker AXS, 2001a) Unit cell refinement on all observed reflections, and data reduction with corrections for Lp and decay were performed using SAINT. (Bruker AXS, 2006) Scaling and a multi-scan absorption correction were done using SADABS. (Bruker AXS, 2004) The minimum and maximum transmission factors were 0.7132 and 0.8990, respectively. A total of 51012 reflections were collected, 3144 were unique (R~int~ = 0.0453), and 3033 had I > 2\s(I). Systematic absences were consistent with the compound having crystallized in the orthorhombic space group Pmn2~1~ or Pmmn. The observed mean |E^2^-1| value was 0.786 (versus the expectation values of 0.968 and 0.736 for centric and noncentric data, respectively). The E^2^ statistics and figures of merit were ascertained to be unreliable due to the presence of two palladium atoms in the asymmetric unit and the presence of twinning. The centrosymmetric space group Pmmn (No. 59) was selected, and confirmed to be the correct choice by successful refinement of the structure. ________________________________________________________________________ Bruker AXS (2004).

(Bruker AXS, 2001b) The asymmetric unit was found to contain two quarter-molecules of (Acetato) (10-benzo[h]quinolinato)palladium(II) dimer, i.e., there are four dimers in the unit cell, each with crystallographic mm2 symmetry, and located at Wyckoff positions 2a and 2b. Since the ligating atoms of the 10-benzo[h]quinolinato ligands are required by symmetry to be compositionally disordered, the N(1) and C(1) atoms were assigned site occupancy factors of 0.5 and their coordinates were refined to the same values. The N(1') and C(1') atoms were treated similarly. All of the nonhydrogen atoms were refined with anisotropic displacement coefficients. The hydrogen atoms were assigned isotropic displacement coefficients U(H) = 1.2U(C) or 1.5U(C~methyl~), and their coordinates were allowed to ride on their respective carbons. This model refined to R(F) = 0.2773, at which point it was obvious that the data were twinned. A Platon/TwinRotMat test indicated 50:50 twinning about [1-10]. (Spek, 2003) Inclusion of the twin law (0-10, -100, 00-1) in all subsequent cycles of least-squares led to a dramatic lowering of R(F) from 0.28 to under 0.03. The refinement converged to R(F) = 0.0282, wR(F^2^) = 0.0701, and S = 1.120 for 3033 reflections with I > 2\s(I), and R(F) = 0.0297, wR(F^2^) = 0.0713, and S = 1.120 for 3144 unique reflections and 183 parameters. The maximum |\D/\s| in the final cycle of least-squares was 0.001, and the residual peaks on the final difference-Fourier map ranged from -0.487 to 1.091 e\%A^-3^. Scattering factors were taken from the International Tables for Crystallography, Volume C.
