✦ Synopsis

In the deprotonated form, trans-[Os IV (tpy)(Cl) 2 (NSC 6 H 3 Me 2 )], the angle Os1-N1-S1 (129.5(2)8) and bond Os1-N1 (1.890(3) ) are relatively unchanged while there are significant changes in the angle N1-S1-C41 (104.3(2)8), and the bonds N1-S1 (1.596(4) ), and S1-C41 (1.784(4) cf. with Os1-Cl1 (2.4139(10), Os1-Cl 2 (2.4007(10), Os1-N11 (2.057(3), Os1-N21 (2.012(3), Os1-N31 (2.065(3)) in [1 A] ).
