“…Crystal structures of the compounds with a P(S)-N-P(S) unit are already known e.g. [(Me 2 N) 2 P(S)] 2 NMe (Alouani et al, 2007), C 6 H 4 (NH)P(S)EtNP(S)(NEt 2 )Et (Bent et al, 1990), [Ph 2 P(S)] 2 N(CHMePh) (Simón-Manso et al, 2002) and NH 2 (NHMe)P(S)N(Me)P(S)(NH 2 ) 2 (Ziegler et al, 1968). In the present publication, we report on the formation and molecular structure of C 24 H 30 N 2 P 2 S 2 , which was observed to be the single product of a complete oxidation of Ph 2 PN(iPr)P(Ph)N(iPr)H with sulfur.…”

A new phosphorothioic triamide structure: P(S)[NHCH₂C₆H₅]₃

The structure of N,N',N''-tribenzylphosphorothioic triamide, C21H24N3PS, (I), and analysis of the bond-angle sums at the N atoms for this compound, and for 74 structures with a P(S)[N]3 skeleton and the N atom in a three-coordinate geometry found in the Cambridge Structural Database [CSD; Groom & Allen (2014). Angew. Chem. Int. Ed. 53, 662-671], are reported. For (I), the bond-angle sum at one of the N atoms [359 (1)°] shows a nearly planar configuration, while the other two show a nonplanar geometry with bond-angle sums of 342 (1) and 347 (1)°. The location of the atoms attached to the nonplanar N atoms suggests an anti orientation of the corresponding lone electron pairs (LEPs) on these N atoms with respect to the P=S group. For 74 structures with a P(S)[N]3 skeleton and with the N atom in a three-coordinate geometry, the bond-angle sums at the N atoms were found to be in the range 293-360°. Among 307 such three-coordinate N atoms, 39% (120 N atoms) have bond-angle sums in the range 359-360°, in accordance with sp(2) hybridization, and 45% (138 N atoms) have bond-angle sums in the range 352-359°, with hybridization close to sp(2). For the orientation of the LEP with respect to the P=S group, the anti orientation was found to be a general rule for N atoms, with the corresponding bond-angle sums deviating by more than 8° from the planar value of 360°. In the title structure, the S atom takes part in intermolecular (N-H···)(N-H···)S hydrogen bonds, connecting the molecules into extended chains parallel to the b axis. The co-operation of one N atom in an N-H···S hydrogen bond as an H-atom donor, and in an N-H···N hydrogen bond as an acceptor, is a novel feature of the crystal structure.

In this study, we relate the contents of the journal Structural Chemistry for the calendar year 2007 and thermochemistry. The year's articles were briefly summarized and a thermochemical comment written to supplement them. Frequently questions were asked and future research was suggested.Keywords Structural Chemistry Á Thermochemistry Á Thermodynamics Á Enthalpy of formation Á Enthalpy of phase change Á Enthalpy of reaction As practiced disciplines, structural chemistry and thermochemistry are very often unrelated. In this study, these disciplines are linked as relations are explicitly made using the contents of the journal Structural Chemistry (Vol. 18) for the calendar year 2007 as a scaffold for our analysis, for our selected articles in the discipline of structural chemistry. These studies have been reviewed by us, where we give them a thermochemical flavor. While this commentary is most generally written in terms of brief summaries of literature papers involving enthalpies of formation and/or reaction, not uncommonly we raise questions and even suggest possible future research. We are not, however, going to give a thermochemical slant on book reviews, honorary dedications, and obituaries although these works will be cited in our text.As such, this article is a sequel to our earlier related reviews of Structural Chemistry for the calendar years 2000 through 2004 [1-5]. Reviews for 2005 and 2006 are currently being prepared. Issue 1In the first article in the first issue of Structural Chemistry for 2007, Hargittai [6] asserted that while research is currently usually carried out in big groups, the most important ideas, observations and discoveries still belong to individuals who have to bring down dogmas or open entirely new areas in science. This may bring solace to the thermochemical community in which research groups are generally small, and the number of new practitioners sadly few.In the past decade, the crystal engineering of multidimensional arrays and networks containing metal ions has achieved considerable progress because of the increased interest in the potential utility of these compounds as zeolite-like materials [7-11], catalysts [12], or magnetic materials [13][14][15]. The thermochemistry of these species is complicated by their inherent complexity: however, estimation approaches of their key thermochemical quantities are increasingly reliable [16]. In the second article of this issue, by Wang et al. [17], the versatility of malonate dianion as a ligand for the construction of extended networks with different topologies dependent on the coordination geometry of the metal ion was discussed. The synthesis and structure of a novel malonate-bridged copper(II) compound in which copper(II) ions have two different coordination environments in a novel three-dimensional (3D) network was described. Metal malonates have been studied from a
