Aminobenzothiazole‐functionalised phosphane 1 and its corresponding phosphorus(V) analogues 2 – 4 were synthesised in high yields. New 1D polymeric salts K[ClC 6 H 3 NC(S)NP(E)Ph 2 ] ∞ (E = O 5 ; E = S 6 ) were shown, by using single‐crystal X‐ray diffraction, to exhibit unique potassium metal ion coordination through either κ 3 ‐N 2 O tridentate (E = O) or κ 2 ‐N 2 bridging (E = S) modes. In contrast, κ 2 ‐NE chelation (E = S, Se) was observed upon complexation to a range of metal fragments including {Ir(η 5 ‐Cp*)Cl} (E = S 8 ; E = Se 9 ), {Rh(η 5 ‐Cp*)Cl} (E = S 10 ; E = Se 11 ), {Ru(η 6 ‐ p ‐MeC 6 H 4 i Pr)Cl} (E = S 12 ), {Ru(η 6 ‐C 6 Me 6 )Cl} (E = S 13 ) and {Pt(PMe 2 Ph)Cl} (E = S 14 ). All new compounds were characterised by a combination of multinuclear NMR, FTIR and microanalysis. Seven compounds were structurally characterised by using single‐crystal X‐ray crystallography.
