We describe the coordination chemistry of the primary phosphine PH 2 C(O)NH 2 (phosphinecarboxamide) towards group 6 transition-metals. Experimental and theoretical studies reveal that this novel species has comparable electronic properties to PH 3 . We describe the coordination chemistry of the primary phosphine PH 2 C(O)NH 2 (phosphinecarboxamide) to form the novel complexes W(CO) 5 (PH 2 C(O)NH 2 ) ( 1 ) and cis -Mo(CO) 4 (PH 2 C(O)NH 2 ) 2 ( 2 ).
