Synthesis and crystal structure of the sodium complex with 2-(diphenylacetyl)indandione-1,3

A Heterobimetallic Anionic 3,6-Connected 2D Coordination Polymer Based on Nitranilate as Ligand

“…In fact, a search in the CSD database (updated to Nov. 2015) [42] shows only 19 of such NaO 4 Na dimeric units, including three NaO 4 NaO 4 Na trimers [43,44,45]. In these NaO 4 Na units, the oxygen bridges belong to different coordinating groups as carboximidato (R-C=NO–Na, in five cases) [46,47,48], hydroxamato (H-C=NO–Na, in three cases) [43,49,50], water molecules (in three cases) [51,52,53], acetato (in two cases) [44,45], oxalato (in two cases) [54], ketone (in two cases) [55,56], alkoxido (in one case) [57], and one more case with two H 2 O molecules and two NO 2 groups [58]. Compound 1 is the first example where the four bridging oxygen atoms belong to an anilato group.…”
