N2  - Recrystallization  of an equimolar mixture of silver(I) perchlorate and 2,2&#8242;:6&#8242;,2&#8243;-terpyridine ( terpy ) from acetonitrile solution yields the golden yellow crystalline adduct shown by a room-temperature single-crystal X-ray study to be [Ag3( terpy )4][( MeCN )Ag( terpy )](ClO4)4. Crystals are triclinic, P&#299; , a 21.48(1), b 14.525(7), c 13.506(8) &#506;, &#945; 68.50(4), &#946; 80.71(4), &#947; 81.66(4)&#176;, Z 2 formula units; R was 0.045 for 9681 'observed' reflections. The complex helical cation is quasi- centrosymmetric with a collinear Ag3 array. The environment of the central silver atom is planar four-coordinate, two short Ag-N distances [(2.198(5), 2.188(5)&#506;] arising from the nitrogen atoms of outer rings of a pair of twisted terpy ligands ; the other two sites are occupied by the nitrogen atoms of the central terpy rings which bifurcate to the other silver atoms [Ag(central)-N(central) 2.624(5), 2.818(5)&#506;; Ag(outer)-N(central) 2.704(4), 2.640(4)&#506;], which are also coordinated by the outer ring nitrogen of the two ligands [Ag-N, 2.266(5), 2.304(4) &#506;]. Coplanar with the latter, each outer silver atom has a further tridentate terpy coordinated [Ag-N(central) 2.362(4), 2.381(4)&#506;; Ag-N(outer) 2.403(6)-2.573(5)&#506;]. The [( MeCN )Ag( terpy )]+ species is also quasi-planar, Ag- NCMe being 2.174(7)&#506;, opposed to the central ring nitrogen [2.331(5)&#506;; Ag-N(outer) being 2.399(7), 2.433(7)&#506;].
